BPSK、QPSK与OQPSK、UQPSK调制识别方法初探

Automatic Modulation Recognition of BPSK,QPSK,OQPSK,UQPSK

近年来,卫星测控链路中大量使用了OQPSK、UQPSK的调制方式。从而,提出了如何区分这两种调制方式与BPSK、QPSK信号的课题。本文借助仿真工具MATLAB分析了这四种信号的二倍频、四倍频频谱特性,并对区分这四种信号的方法进行了初探。

BPSK, QPSK, OQPSK, UQPSK are used in TTC （Track Telemetry and Control） of Satellite Link in recent years. This paper analyses the spectrum feature of BPSK, QPSK, OQPSK, UQPSK. And study the method of the classification algorithm.
