From university academician to chief academician

In the laboratory!

Ye Fei looked at the ten people under his command.

There were 500 people who came to seek refuge with Ye Fei. Ye Fei divided the 500 people into ten groups, each with fifty people.

Ye Feidao: "Our current work is to develop a new ultra-wideband pulse technology."

The carrier-free pulse technology is called ultra-wideband, and the carrier-free pulse technology is called ultra-wideband pulse technology.

“The so-called ultra-wideband pulse technology refers to ultra-wideband waveforms.”

"Based on the research on ultra-wideband pulse technology at home and abroad over the years, as far as I know, the world's most advanced ultra-wideband pulse technology is developed through orthogonal basis functions."

Whether it's ultra-wideband pulse technology or finding new pulses.

All are studied and found through mathematics.

"But I think that orthogonal basis functions are not perfect for the study of pulses."

"The most perfect one is through the Gaussian derivative function."

Everyone was noisy for a moment, discussing with each other softly.

Ye Fei didn't stop him either. He didn't say anything, and Ye Fei believed that scientific research needed to have opposing voices.

Only by having opposing voices can we find the most appropriate research direction among the many ideas.

After a moment, a person said: "Professor Ye, using orthogonal basis functions to study ultra-wide pulse technology has been scientifically verified. For decades, scientists have found that orthogonal basis functions are the most suitable for studying communication technology."

"And you proposed using a Gaussian derivative, and I want to know why."

Orthogonal basis function is a common mathematical tool. Its algorithm can find mutually orthogonal basis functions in high-latitude space, so that its basis functions can be used to represent arbitrarily complex data.

It can be used in the fields of signal processing and machine learning...

Ye Feidao: "As we all know, orthogonal basis functions belong to the field of linear algebra, which is usually used to study space and latitude."

"In this regard, I admit that orthogonal basis functions are indeed very suitable for the field of communications."

"But last year, I conducted a study and found that using Gaussian derivative functions is more appropriate than orthogonal basis functions."

"The orthogonal basis function uses an algorithm to calculate the spectrum utilization rate and operation time of the pulse."

"Orthogonal basis functions have strong flexibility and high utilization rate in terms of pulses."

"The Gaussian derivative function has a higher utilization rate than the orthogonal basis function in terms of pulses. It has half the utilization rate, while the orthogonal basis function has a utilization rate of 30%."

"In terms of flexibility, it can find the optimal waveform and conduct MATLAB simulation of the linear combination of the normalized Gaussian pulse derivative function."

"So, the properties that the orthogonal basis function has are also possessed by the Gaussian derivative function, and are even better than it."

"Because of this, I say that it is more appropriate to use Gaussian derivative functions than orthogonal basis functions."

After hearing this, everyone looked at each other in confusion.

Although Ye Fei made wild claims about the Gaussian derivative function, they had not conducted experiments and were not sure whether what Ye Fei said was true.

Ye Feidao: "In this way, I will write for you a basic formula for studying ultra-wideband using Gaussian derivative functions. After reading it, you will be able to determine its advantages over orthogonal basis functions."

Everyone nodded and said: "Okay!"

Ye Fei found a pen and paper and wrote down a set of formulas on it.

"Everyone, please take a look!" Ye Fei handed them the paper with the formula written on it.

Everyone looked at the formula and discussed with each other.

One person said: "Look at this set of formulas. If you plug them in, you can determine the signal where the ratio of broadband to center frequency exceeds 50%."

The ratio of broadband to center frequency of ultra-wideband is more than 20%.

This formula can make the ratio of broadband to center frequency exceed 50%, which means that the network signal studied using this formula is very high.

"Also, the bandwidth limit can reach 200GHz."

"This means that the upper limit of research is higher, and it is also suitable for Li-Fi's requirements for network speed."

The network speed of Wi-Fi6 is 10GHz, and the network speed of Li-Fi is 100GHz.

After a while, everyone handed the paper to Ye Fei and said: "Professor Ye, your idea is right. We agree with your point of view and use Gaussian derivative functions to study ultra-wideband pulse technology."

Ye Fei smiled and said: "Don't worry, we will definitely be able to develop ultra-wideband pulse technology."

"Yeah!" Everyone nodded.

Academician Ning's office!

Ye Fei knocked on the door and walked in after hearing a voice asking him to come in.

Academician Ning saw Ye Fei walking in and smiled: "Professor Ye, please sit down!"

After Ye Fei sat down, Academician Ning asked, "How is it? Have you finished talking to the people in your group?"

"The discussion is over." Ye Feidao said: "We finally decided to use Gaussian derivative functions to study ultra-wideband pulse technology."

"Gaussian derivative function?" Academician Ning said in surprise: "Don't use orthogonal basis functions?"

Ye Fei shook his head: "No, because I found through research that Gaussian derivative functions are more suitable for studying communication technology than orthogonal basis functions."

Academician Ning smiled and said: "Don't doubt people, don't doubt people. I won't ask you why you used the Gaussian derivative function. I only want the results."

"I don't care what method you use, I just want you to develop ultra-wideband pulse technology."

Ye Fei smiled and said: "Don't worry, I will definitely research it."

Academician Ning said: "Do you need any help from me?"

"Funding, supercomputing, talent."

"I am not sure about the abilities of the five hundred people who are following me now. If I need talents in certain fields later, I hope you can provide them to me."

"Yes!" Academician Ning said, "No problem. As long as you need any talents in the future, I can provide them to you."

“I don’t have them here, I will dig them out from other places through my connections.”

"Moreover, this project is a national key project, and many people above are keeping an eye on it."

"As long as we have talents in the country, we will dig them out for you."

"I will allocate any amount of funds you need."

"The supercomputer uses the supercomputer from the Chengdu Supercomputing Center."

The Chengdu Supercomputing Center was built in the past two years and is located in the southeast corner of Xinglong Lake in Tianfu New District.

"Then I will call the supercomputing center. If you want to use it, go directly to them and they will let you use it."

"Okay!" Ye Fei smiled and said, "Then I have no other requirements."

Academician Ning said: "Look, it's already past ten o'clock. You must be hungry!"

Ye Fei touched his stomach and smiled sheepishly: "If you didn't tell me, I wouldn't have realized it. I'm really hungry."

Ye Fei was busy all day long, and when he was so busy he even forgot about hunger.

"I didn't think it through well. Come on, let's go eat."

After saying that, they stood up and walked outside.

The school cafeteria was closed long after ten o'clock.

So, Ye Fei and the others went to a restaurant near the school to eat.

After eating, the two of them returned to their residences to rest.

The next day, in the lecture theater!

Ye Fei summoned all the team members, all five hundred people.

Ye Feidao: "After my communication with the leaders of each group, it was finally decided to use Gaussian derivative functions to study ultra-wideband pulse technology."

"I think you all know this!"

Everyone nodded, they all knew the news last night.

At first they wondered why the Gaussian derivative function was used.

After the team leader's explanation, they understood why the Gaussian derivative function was used.

Indeed, using Gaussian derivative functions to study the field of communications is more appropriate than orthogonal basis functions.

Ye Feidao: "Since you know, I won't explain it again. I'll talk about my research habits."

"In all the research that I participate in, as long as it is a research that I lead, I will state the research direction at the beginning, and the main formula will be derived by me alone."

"Ugh..." Everyone looked at Ye Fei in surprise.

No, you can tell me the research direction from the beginning?

You already know the research direction before you start researching?

According to common sense, the research direction can only be known through continuous exploration in research.

Rather than knowing the research direction before starting research.

Unless the research is very simple or has been done before.

But now they are studying ultra-wideband pulse technology, which is difficult to study and they have never studied it before.

Therefore, at this moment, Ye Fei said that the research direction was very unreasonable.

What is even more unreasonable is that Ye Fei had to derive the main formula alone.

The main formula is the most difficult part of the research. Ye Fei also has to derive it by himself?

You are a human being, not a god.

Everyone looked at Ye Fei with suspicion.

Ye Fei didn't care about everyone's looks. This was Ye Fei's first contact with them. Many of Ye Fei's behaviors seemed unbelievable to them.

But Ye Fei did it very easily.

It doesn't matter that they doubt Ye Fei now, time will prove everything.

Ye Feidao: "The research is divided into three parts."

"1. Determine the research principles."

"2. Pulse of ultra-wideband system."

"3. Simulation results and analysis."

"Let's start with the research principles."

“The first thing we need to know is the concept of ultra-wideband.”

"The second is radiation masking of ultra-wideband signals."

"First let's talk about the concept of ultra-wideband, and now about ultra-wideband..."

Ye Fei spent the whole day in meetings with the team members, explaining to them in detail how to conduct research.

Many people thought: "You have already explained it in such detail. All we have to do is teach us how to study it step by step. Ye Fei has never studied ultra-wideband pulse technology, right?"

They found that Ye Fei's words were too detailed, as if he had personally experienced the research of ultra-wideband pulse technology.

In fact, Ye Fei has personally experienced the research of ultra-wideband pulse technology.

Rather, Ye Fei has come into contact with too many scientific researchers over the years and absorbed too much inspiration.

A lot of research, even if Ye Fei has not personally experienced research.

But as long as Ye Fei went to study, a lot of inspiration burst out in his mind instantly.

Because of this, when Ye Fei told them about the research on ultra-wideband pulse technology, they sounded like Ye Fei had experienced it personally.

Of course, after listening to Ye Fei's detailed explanation, they already knew how to study next.

They are also very easy to research.

This is equivalent to Ye Fei telling them the answer, and then they just copy it.

Of course, the difficulty of copying this copy and copying the homework are naturally different.

But it is definitely countless times simpler than their previous research model.

Ye Feidao: "Okay, that's it for today. If there is anything to add in the future, I will call you back again. Dismiss the meeting!"

After saying that, Ye Fei stood up and left.

The next day, they began to devote themselves to research.

This time Ye Fei also took action personally.

In the past, Ye Fei rarely interfered in the team members' research after telling them the research direction and main formula.

Ye Feixin said: "It's no good if you don't get started. This research is too important."

"Wi-Fi7 can restrict 5G, so Li-Fi must be researched before Wi-Fi7 comes out."

Not to mention the importance of 5G, Beiliguo is studying Wi-Fi7.

If Wi-Fi7 comes out, there will be nothing to resist Wi-Fi7 by then.

Something big will happen at that time, and the consequences will be very serious.

Because of this, Ye Fei attaches great importance to Li-Fi research.

Even more important than asymmetric encryption algorithms.

After all, there is no sense of urgency in research on asymmetric encryption algorithms.

And Li-Fi research has a sense of urgency.

Ye Feixin said: "Beili Country has been developing Wi-Fi 7 for six or seven years, and it should be available soon."

"I must develop Li-Fi before Wi-Fi7 comes out."

Beiliguo, Wi-Fi Alliance, Wireless Communication Technology Research Institute!

director's office!

Saira Berger is chief scientist at the Wireless Communications Technology Institute.

He is an emeritus professor of electronic communications at MIT and a fellow of the National Academy of Sciences.

Received the Marconi International Research Foundation Award.

The Marconi International Research Foundation Award is the highest award in the field of communications, equivalent to the Nobel Prize in the field of communications.

Let’s talk about the difference between fellows and academicians.

In Beiliguo, there is a term limit for membership, and academicians are for life.

The status of fellows is one level lower than that of academicians.

Berger said excitedly: "Dean, in nearly a year, Wi-Fi7 will be developed."

"The research on Wi-Fi 7 has cost us countless efforts, and now we are finally succeeding."

The dean smiled and said: "Very good, Berger. When Wi-Fi7 is successfully developed, I will report your contribution to the boss."

"When the time comes, if you run for dean of the MIT School of Engineering, the higher-ups will help you and 100% let you pass."

"Thank you!" Berger smiled: "I will definitely succeed."

"As long as Wi-Fi7 comes out, 5G will be greatly limited."

"Yes!" The dean nodded: "Even if Xia Guo has 5G, but we have Wi-Fi7, we can limit the speed of 5G."

"Yes!" Berger nodded: "By the way, I heard in Xia State that someone is researching Li-Fi. Is this news true?"

The dean said disdainfully: "It's true. Li-Fi has huge drawbacks. So what if it's researched out?"

“It’s useless to study something that cannot be popularized.”

"I really don't understand what these people are doing studying Li-Fi."

"Yeah!" Berger nodded.

Neither of them would have imagined that Li-Fi would have a devastating impact on Wi-Fi7.

In their minds, they believe that Li-Fi has fatal shortcomings. It cannot be popularized after research, which means that it is useless even after research.

Berger said: "I heard that there is a person named Ye Fei in Xia State who developed an asymmetric encryption algorithm. Is this true?"

The communication field belongs to the computer field, and the asymmetric encryption algorithm belongs to the blockchain field.

The blockchain also belongs to the computer field.

Therefore, there is an intersection between communication and blockchain.

"Yes!" The dean nodded: "This news is true, and many people in the computer circle know it now."

"But only the theoretical part of his research has been released, and the applied part will not come out until several years later."

"I heard that this person named Ye Fei is only 26 years old this year."

"Yes." The dean said: "Many people compare him with Ethereum's V God, saying that he is another prodigy of the blockchain."

Berger said: "Mochizuki Shinichi's consensus mechanism, Xia Guoshutu Blockchain Research Institute's distributed ledger, Ethereum's smart contract, plus Ye Fei's asymmetric encryption algorithm."

"What do you think would happen if they worked together?"

"It is possible to start the Web3.0 era."

“Plus 5G support!”

The dean said with some horror: "That will be the end of the world!"

Mochizuki Shinichi, Tree Map, Ethereum and Ye Fei.

They can start the Web3.0 era.

5G is the energy of Web3.0 and supports the development of Web3.0.

But in this world-changing change, Beili Country had no involvement.

In particular, three-fifths of them were participated by Xia Guo.

This is really the end of the world for Beili Country.

Mochizuki Shinichi is from Japan, Shutu is from Xia Country, Ethereum V God is from Northern Russia and now lives in Canada, Ye Fei is from Xia Country, and 5G is from Xia Country.
