摘要

随着通信信号调制的多样性和复杂性，解决调制识别问题显得更加重要和迫切。基于功率谱的m谱特征，研究了PSK信号的调制识别。利用Matlab对BPSK信号、QPSK信号、OQPSK信号、DQPSK信号和π/4-DQPSK信号的m功率谱进行了仿真。通过仿真结果总结了这五种信号的M功率谱特征。在此基础上，设计了一套可用于PSK信号类内识别的识别规则和识别流程。

Research on Modulation Mode Identification of PSK Signal Based on M-th Power Spectrum Features

With the variety and complexity of communication signal modulation, it is more important and urgent to solve the problem of modulation identification. The modulation identification of PSK signal is studied based on the features of M-th power spectrum. The M-th power spectrum of BPSK signal, QPSK signal, OQPSK signal, DQPSK signal and π/4-DQPSK signal are simulated by Matlab. The features of M -th power spectrum of these five signals are summarized through the simulation results. Based on the results, a set of identification rules and identification process are designed, which can be used for intra-class identification of PSK signals.
