A locally optimum receiver structure is derived for the coherent detection of continuous phase frequency shift keying in non-Gaussian noise. Performance of the receiver, which consists of a zero-memory nonlinearity followed by a correlator, is evaluated for a number of important noise models. The effects of varying the observation interval and modulation index on receiver error probability are determined.
