Abstract : This note is proposing a new algebraic demodulation method for full response CPM signals in AWGN channels. The method is based on a new estimation/identification theory that has also been used for channel identification and signal deconvolution. The signals and noises are considered to be deterministic and we find an explicit formula for the recovery of the transmitted symbols. Based on this formula the symbols are recovered blindly, needing only the knowledge of the modulation index. The method is not only simple and robust with respect to noises, but also very fast: it enables its implementation on-line. It can also be used for coherent and non-coherent demodulations. The method, which is applied to the CPFSK and LRC families of signals, is showing good results.
