Sequence detection algorithm for CPM based on Walsh signal space decomposition
基于Walsh信号空间分解的CPM序列检测算法*

This paper proposed a sequence estimation algorithm which was based on the decomposition of the CPM signal in the Walsh signal space.Its front end was just the ordinary linear receiver followed by a subinterval sampler,eliminating the need for the matched filters.Defined a rule concerning the number of Walsh functions that must be used by analyzing minimum projection distance loss,which was proved availably by the simulation results.
