摘　　要：在无线电信号分析、监测中,信号的调制机制识别是其中的关键。多进制数字相位调制信号(MPSK)的识别在实际应用中需求广泛,能准确识别出MPSK的具体调制方式意义重大。本文针对接收信号为MPSK时,通过基于星座图恢复处理及斑点检测的组合算法,精确区分不同多进制数字相位调制信号。通过对BPSK、QPSK、8PSK信号的仿真分析,证明本文所提算法能准确识别出各种多进制数字相位调制信号。Identifying the modulation mechanism of the signal is crucial for wireless signal analysis and monitoring.The recognition of Multi base Digital Phase Modulation signals(MPSK)is widely needed in practical applications,it is of great significance to accurately identify the specific modulation method of MPSK.This article focuses on the precise differentiation of different multi base digital phase modulation signals using a combination algorithm based on constellation recovery processing and speckle detection when the received signal is MPSK.Through simulation analysis of BPSK,QPSK,and 8PSK signals,it is proven that the algorithm proposed in this paper can accurately identify various multi band digital phase modulation signals.
