A new computational approach for the demodulation of CPM signal
Michel Fliess, Mamadou Mboup, Hugues Mounier · 2004
We present a straightforward algebraic setting for the demodulation of continuous phase modulated signals over an additive noise channel. We are exploiting the form of the continuous-time signal and the developments rely on classical deterministic numerical analysis. No assumption is required for the statistical properties of the signals and noises. The information-bearing symbol data are identified on-line, directly from the continuous time signal, without any sampling process. The approach is very simple to implement. It is robust with respect to additive noise disturbance. Simulation results are presented.
