Abstract
To double the noise immunity of digital radio communications of frequency-managed transport systems, it is proposed to use the method of coherent detection of frequency-manipulated signals (FMn) instead of envelope detection. At the same time, the reverse operation of the coherent detector of signals with absolute phase manipulation (PMn) at 180° is achieved due to the post-detector signal processing. Such processing is possible with participation of a frequency detector on frustrated circuits with a trigger connected to it.
