AMPLITUDE SHIFT KEYING DEMODULATOR Russian patent published in 2022 - IPC H03D5/00 H04L27/38 

FIELD: radio communications.

SUBSTANCE: invention relates to radio communications and can be used in the demodulation of amplitude shift keying (ASK) signals. The effect is achieved due to a set of essential features in the claimed device, due to which an adaptive change in the decision threshold values ​​occurs based on the results of summing the amplitude values ​​of the signal packages processed on the current and previous cycles, which makes it possible to receive and demodulate ASK signals in channels with fading. Wherein the value of the adaptive decision threshold for the duration of each signal message is determined as a quarter of the result of summing the amplitude of the current and previous pulses of the sequence formed at the reception.

EFFECT: providing the possibility of receiving and demodulating ASK signals in channels with fading.
