Abstract. Method of useful signal parameter discrete-continuous non-parametric filtering, using evolutionary equations, fast-Fourier-transform algorithms and patch functions, is developed, allowing to get practically engineerable schemes of optimal receivers for location, navigation, communications and information transmission problems under the conditions of conventional (parameter) Gaussian approximation invalidity. Example of block scheme synthesis of receiver for signal with phase-difference modulation is given.
Key words: Markov process, discrete-continuous process, posteriori probability density, evolutionary equation, Markov homogeneous chain, Fokker-Plank-Kolmogorov equation, Stratonovich equation, phase-difference modulation, fast Fourier transform, patch function.
