摘　　要：在CPM信号的非协作通信中,需要对接收信号进行精确的调制指数估计。针对传统的调制指数联合估计算法三维空间搜索复杂、不能实时估计的问题,提出一种分步联合估计算法,极大地降低了计算复杂度,能更好地满足实时性需求。In the non-cooperative communication of CPM signals,it is necessary to accurately estimate the mod-ulation index of the received signal.Aiming at the problem that the traditional joint estimation algorithm of mod-ulation index is complex in three-dimensional space search and can not be estimated in real time,a step-by-step joint estimation algorithm is proposed,which greatly reduces the computational complexity and can better meet the real-time requirements.
