On the other hand, the United States and other western countries took the express trains in age of steam, the electric age and the information technology age, and seized a lot of resources first. Now, in the wave of the fourth scientific and technological revolution with 5G technology as the core, China can finally catch up and stand at the bow of history again.
the rapid development of p>5G technology is inseparable from the hard work of a large number of scientific workers behind it. In the long research and development career, there are countless "geniuses" who silently dedicate their youth to this technology, but fortunately, their efforts have not been in vain. With the disclosure of 5G technology, the names of the researchers involved in this project have gradually become familiar to the public and gained the glory they deserve.
among these people, there are hard-working seniors who have laid a solid foundation for 5G technology, as well as geniuses who are enterprising, talented and constantly making breakthroughs in technology. In this team, Shen Yifei, a 21-year-old doctoral student, has successfully attracted people's attention because of his rich scientific research achievements and surprisingly young face.
The teenager "learns God"
In p>1997, Shen Yifei was born in an ordinary family in Handan, Hebei. As we all know, Hebei is a big province for college entrance examination, and it is a province with great learning pressure. There is no 985 university in Hebei, but the only 211 university, Hebei University of Technology, is located in Tianjin, a municipality directly under the central government adjacent to it. Every student in Hebei is facing a war without smoke when competing for educational resources.
But for the young Shen Yifei, this kind of pressure not only didn't overwhelm him, but made him feel like a duck to water, like a sponge, constantly absorbing the knowledge he needed.
At the age of 2, he learned simple arithmetic under the education of his parents, and his literacy was also the best among his peers. At the age of 4, although he has not officially entered school, he has already started to teach himself primary school courses; At the age of 5, he was admitted as a first-year student by a local primary school, and he was a well-known "learning god".
Unlike many child prodigies, Shen Yifei's parents didn't repeatedly set the goal of "advanced placement" and "cross-examination" for their children because of vanity, but gave him sufficient space for independent choice, and even encouraged him to leave school more often and cultivate his hobbies. In this way, Shen Yifei participated in the school's youth choir, learned to play erhu and play Go, and spent six years with his classmates and friends in primary school without any worries.
In p>28, China successfully hosted the Olympic Games. At the same time, 11-year-old Shen Yifei decided to take part in the assessment of the youth department of Handan No.1 Middle School and successfully became a member of the youth class. The juvenile class in Handan No.1 Middle School is specially set up for children who are academically gifted. It has its own unique five-year academic system and can take the college entrance examination at the age of 16. However, Shen Yifei's learning progress is even faster than that of his classmates. In the second year of high school, Shen Yifei, who was only 15 years old, took the initiative to sign up for the college entrance examination and entered the information science and engineering major of Wu Jianxiong College of Southeast University with excellent results.
"Studying for the Rise of China"
In the first year of college, Shen Yifei was no different from other students except that he was young. At that time, Shen Yifei did not have a clear ambition. Influenced by this drift mentality, Shen Yifei, who had no goal, became a sophomore, and even began to fail. This incident greatly hit him and made him look back on his college life.
Shen Yifei realized that it is not enough to "learn". Only when one knows why he studies can one always maintain his enthusiasm for learning. At this time, Professor You Xiaohu, the "head" of China's 4G technology, handed an olive branch to Shen Yifei, which enabled Shen Yifei to find the direction of his efforts again.
After joining Professor You Xiaohu's R&D team, Shen Yifei quickly found his life goal again. Soon, with the change of his mentality, his grades improved rapidly. In his junior year, he became the only student in information science and engineering major who won the first place in all subjects in the past ten years. He also won various honors such as "three good students" and "top ten students", and was recommended as a graduate student with the first comprehensive score of his major.
While studying under Professor You Xiaohu, Shen Yifei gradually came into contact with the research and development of 5G technology. Following Professor You Xiaohu's team, in 216, 19-year-old Shen Yifei successfully won the world's top academic award and the IEEEDSP Best Student Thesis Award; In 218, 21-year-old Shen Yifei continued his studies and began to pursue a doctorate.
During this period, Shen Yifei published two international conference papers and one SCI paper, and applied for three national invention patents. Among these achievements, three technical patents are particularly eye-catching. These three patents can be said to be important conditions for breakthroughs in 5G technology.
The research center of the team led by Shen Yifei is to build a polarization code platform for general processors. The technology developed by Shen Yifei has increased the computing speed from two seconds to one second to calculate 2, sets of data, which not only broke the strict technical barrier built by the West on China in the chip field, but also left the other side far behind, solved the problem of time delay in data transmission, and became the magic weapon for China's 5G chip technology, greatly promoting the related industries.
Conclusion:
As the saying goes, "Youth is strong. Then the country is strong. " Shen Yifei is a rare genius, but his success, in addition to his talent in learning, is also attributed to his knowing why he "studies". The so-called "studying for the rise of China" has never been an empty talk. Only by setting a lofty goal can a person not get lost on the road of life.
It is precisely because there are countless people like Shen Yifei that China can make rapid technological breakthroughs. On June 17th, under the leadership of Liu Yunjie, an academician of China Academy of Engineering, China's 5G millimeter wave chip was officially developed successfully, and the initial powder packaging and testing have been completed, which greatly reduced the original channel cost and will be put into use next year.
The invention of this millimeter-wave chip further enhances the possibility of popularization and application of 5G in urban construction, and successfully solves the communication transmission problem of "the last 1 meters" in the era of centimeter-wave chips.
on the other hand, the United States, because it has invested a lot of time and money in the centimeter wave band, has gone into the misunderstanding of paying attention to one thing and losing another. On the day when the research and development of the 5G millimeter-wave chip was announced, US President Trump and US Secretary of State Pompeo immediately announced that Huawei would be allowed to cooperate with American companies to formulate 5G network standards.
It can be said that in the era of the fourth scientific and technological revolution with 5G technology as the leader, with the efforts of a large number of young scientists represented by Shen Yifei, China once again seized the historical opportunity and embarked on the cusp of the times. They have been achieved by the times and are also the guides of the times.
