摘　　要：随着现代通信的发展,数字调制方式的识别在无线电监测、信号检测等领域的需求日益增加,作为信号筛选和解调的基础,在通信对抗中意义重大。在已知的几种调制信号中,MPSK和MQAM信号的应用最为广泛,设计出以接收信号的高阶累积量作为特征来识别MPSK和MQAM等数字调制方式,进行了理论推导,开展了MATLAB仿真工作,验证了方法的可行性和可靠性,实现了对数字信号调制方式的识别。With the development of modern communication,the recognition of digital modulation has become increasingly prominent in fields such as radio monitoring and signal detection.As the basis for signal screening and demodulation,it is of great significance in communication confrontation.Among the several known modulation signals,MPSK and MQAM signals are most widely used.Therefore,the high-order cumulants of the received signals are used as features to identify MPSK and MQAM digital modulation signals.Theoretical derivation is made,and MATLAB simulation is performed to verify the feasibility and reliability of the method and realize the recognition of the digital signal modulation type.
