FIELD: radio engineering, communication.
SUBSTANCE: demodulation method uses an analog-to-digital conversion, the multiplication of instantaneous discrete signal values with Vm - the parameter of the characteristic function of the signal, the conversion to obtain the sine and cosine functions of the products, the accumulation and averaging of the current values of the sine and cosine functions over a time interval equal to the duration of the symbol "0" and "1", comparison with the predetermined thresholds B(Vm, T) is imaginary and the estimates A(Vm, T) of the real part of the characteristic function.
EFFECT: increasing of noise immunity of systems of transfer of the discrete information on communication channels.
