Spectral Correlation Analysis of MPSK Signals
-
摘要: 该文着重对于多进制频移键控(MPSK)信号的谱相关特性进行了分析，并改写了MPSK信号表达式，由此得到BPSK,QPSK,8PSK,16PSK信号的谱相关密度函数；应用谱相关函数的工程计算公式，对这4种信号的谱相关特性进行了仿真，验证了得到的谱相关密度函数的正确性。

Abstract: This paper put great emphasis on spectral correlation of MPSK signals. The cyclic spectrum density function of BPSK, QPSK, 8PSK, 16PSK signals based on a new MPSK signal expression is proposed; Extensive computer simulation of four signals based on engineering calculation formula of the spectral correlation function show the accuracy of cyclic spectrum density function. -
