    Site selection analysis of radio monitoring stations to BDS based on STK orbital prediction data by Qi ZHANG, Hui LIN

    Published 2018-05-01
    “…BeiDou navigation satellite system (BDS) is a global navigation satellite system constructed and operated by China.At present,BDS is able to provide location,navigation and time service in Asia-Pacific,and will provide global service in 2020 as planned.As the fact of the rapid development of satellite communication technology,the spectrum and orbits of satellite are increasingly crowed.Therefore,it is vital to perform spectrum monitoring to BDS.Based on the STK orbital prediction data,the access time of the 14 non-GEO satellites in BDS to 9 Chinese cities in 10 days was collected.Group analysis according to different satellites and different cities,and similarity analysis within different cities were performed using the R programming language.At last,preliminary advices on site selection were provided according to the data analysis results.…”

    GAN-based channel estimation for massive MIMO system by Yuxiu HUA, Rongpeng LI, Zhifeng ZHAO, Jianjun WU, Honggang ZHANG

    Published 2021-06-01
    “…As a key technology of 5G, massive MIMO system can significantly improve spectrum efficiency and energy efficiency by equipping a large number of antennas in base stations.However, in massive MIMO system, accurate channel estimation faces severe challenges.In order to estimate the channel accurately when the pilot sequence length is smaller than the number of transmitting antennas and the channel noise is strong, the estimation method N2N-GAN was proposed.N2N-GAN firstly denoised the pilot channel at the receiving end, and then used the conditional generative adversarial network to estimate the channel matrix according to the denoised pilot signal.Simulation experiments show that N2N-GAN achieves better robustness against noise compared with traditional channel estimation algorithms and deep learning-based methods.Meanwhile, it can adapt to scenarios with fewer pilot symbols and more antennas.…”
