METHOD OF RECEIVING SIGNALS OF RELATIVE PHASE TELEGRAPHY IN DEVICES FOR RECEIVING SIGNALS WITH PHASE MANIPULATION Russian patent published in 2021 - IPC H03M13/00 

FIELD: telecommunications.

SUBSTANCE: method of receiving signals of relative phase telegraphy in devices for receiving signals with phase manipulation is proposed, according to which the RPT input signal is simultaneously fed to the inputs of the reference coherent voltage generator (hereinafter – RCVG) and the phase detector (hereinafter – PD), in which the input signal is coherently detected using the reference coherent voltage from the RCVG output. The video signal from the PD output is fed to the regenerator, providing registration of a sequence of binary characters at the moment of receipt of clock pulses from the output of the clock frequency allocation unit to the clock inputs of the regenerator and the subsequent code converter (hereinafter – CC), in which the binary sequence is recoded from the output of the regenerator in order to remove relativity. The output of the CC is the output of a demodulated binary signal, while an additional demodulated signal from the output of the CC, the sequence of clock pulses from the output of the clock frequency allocation unit and the video signal from the PD output are fed to the corresponding inputs of the additionally introduced error detection and correction unit.

EFFECT: increased noise immunity of signal reception.
