Analysis on the Effect of Phase Noise on the Performance of Satellite Communication and Measurement System by Xuan Liu, Hongmin Lu, Yifeng He, Fulin Wu, Chengxi Zhang, Xiaoliang Wang

“…A communication measurement simulation system is built, and a discrete sequence simulation analysis method combining frequency domain and time domain is provided, and the coupling relationship of key indicators such as phase noise, thermal noise, communication data rate, modulation method and bit error rate is synthesized. The results show that the BER of the QPSK/BPSK communication system will not be significantly reduced if the phase jitter RMS caused by the phase noise is less than 5 degrees, so 5 degrees can be used as a reference for the decomposition of the carrier SSB phase noise index. …”
