  The technique of SNR estimation is one of key technolo-gies in adaptive frequency hopping system.The methods of channel quality estimation for nonlinear continuous phase modulation(CPM)signals exists some limitations.Therefore,the algorithm of channel quality estimation for CPM signals is worthy of further study.Some similar phase characteristics between sampling CPM and MPSK motivates us to propose a channel estimation algorithm with applications to nonlinear CPM using linear modula-tion signal processing.
