不同干扰对QSPK解调性能的影响分析
Analysis on Different Jamming Effects on QPSK Demodulation Performance
摘要
Abstract
With the rapid development of digital satellite communication,QPSK become an important modulation of digital satellite communication system,and its demodulated performance has been given more and more public concern. The demodulated performance of QPSK signal is mainly analyzed under the digital modulated jamming,and the statistical distribution of jamming signal make demodulated performance worst,and the statistical distribution also accords with the characteristics of QPSK modulated signal. Numerical results are presented in order to validate the theoretical inferences presented and compare it with various modulated jamming and AWGN jamming.关键词
