The method of signal processing of relative phase modulation

The new method of signal processing of relative phase modulation is proposed. Unlike to classical methods the proposed one realizes the processing of the low-frequency modulating oscillation when sequential samples distorted by the additive noise are correlated.

The proposed method eliminates the hardware that implements the classical methods and allow to use only one signal processor. The probability of error, which characterizes the noise immunity of radio systems based on the implementation of the proposed method is calculated.
