Continuous phase modulation (CPM) is a modulation with constant-envelope waveform and phase continuity, and is applicable in wireless communications for its excellent characters as high bandwidth and spectral efficiency. Based on analysis of CPM signals model, the calculus modulation method is studied. The theoretical derivation, almost without any prior information or parameter in formation, could realize blind demodulation, and the simulation results show that this estimation/identification method could reduce the complexity of the receiver, so is a good way for CPM signal deconvolution
