FIELD: radio engineering, communication.
SUBSTANCE: digitized samples of the received signal on the duration of each sending are divided into two sequences, for each of which their parameters are calculated, which are compared with the previously calculated threshold. The final decision about the information symbol is taken according to the comparison results of the sequence calculated signal parameters of which exceed the previously calculated threshold only at the frequency positions corresponding to either the information unit or the information zero.
EFFECT: providing of detection and decision-making about the transmitted information symbol in the conditions of imitation interference in signal transmission radio channels with two-position frequency manipulation.
