Chinese Academy of Sciences Shanghai Advanced Research Institute Develops Smart Spectrum Sensing Technology For 5G Communication
Spectrum sensing will play an important role in future wireless communication systems, and it will help solve coexistence issues and optimize spectrum efficiency. However, 5G communication will involve different scenarios, different features, and different needs, which makes it difficult for spectrum sensing methods to flexibly serve a variety of applications while maintaining good performance. The scarcity of spectrum resources is still a key challenge for 5G communications.
Driven by this challenge, the research team led by Professor Hu Honglin and Professor Xu Tianheng of the Shanghai Institutes of Higher Education, Chinese Academy of Sciences has proposed a novel spectrum sensing technology, seeking a feasible way to strengthen the concept of learning Combined with advanced spectrum sensing methods to optimize the performance of cognitive wireless networks in multiple scenarios in 5G communications.
The research results were published in the latest issue of IEEE Wireless Communications, entitled "Intelligent Spectrum Sensing: The Combination of Enhanced Learning and Automatic Repeat Sensing in 5G Communication".
The research team analyzed the different needs of several typical 5G scenarios, and classified three dedicated models based on the optimization goals of spectrum sensing technology.
In order to adapt to various optimization goals, the research team designed the architecture of smart spectrum sensing technology to try to take into account both instability and adaptability issues. Numerical results show that the proposed sensing technology can adapt to various scenarios with different optimization goals.
The research results have certain practical application value. They have been used in the SEANET system jointly developed by the Chinese Academy of Sciences and the Chinese Academy of Sciences and the Shanghai University of Technology-Alpha Network. The research results also help the further deployment and promotion of 5G and next-generation communication systems in China.
