FIELD: information technologies.
SUBSTANCE: signal is received, filtered and its amplitude is balanced, a reference signal is generated, and its correlation function is calculated with a received signal. Then the correlation function is integrated in series, and its value is fixed. A module of difference between values of correlation functions is calculated at different time intervals, and it is compared with a corrected threshold value, which is calculated by algebraic summation of a preset threshold value and a calculated deviation determined by the value of "one" or "zero" at the outlet of the demodulator. The threshold value is corrected at each stage of decision making depending on the ratio of "ones" and "zeros" in a demodulated signal.
EFFECT: higher noise immunity of the method of signal demodulation with relative phase modulation.
