FIELD: communication technology.
SUBSTANCE: invention can be used in communications.
The technical result is to increase the speed of information exchange under the influence of interference. To do this, the input mixture of signal and noise is branched into two identical components. The first component in the main channel is multiplied by a copy of the signal, then integrated, processed by the signal power measurement method, the signal is squared, after squaring the received signal is filtered by a low-pass filter (LPF) and simultaneously filtered by a band-pass filter (BPF). The signals that have passed PF and LPF are counted. These values subtract one from the other. The subtraction results are summarized and stored. The second term is multiplied by the signal orthogonal to the signal used. The received signal is integrated. After that, processing is carried out by the signal power measurement method. From the value of the estimate of the power of the mixture of signal and interference received in the main channel, the value of the estimate of the power of the interference obtained in the additional channel is subtracted. A decision is made about the presence of a signal by comparing the obtained value of the signal power estimate with a threshold.
EFFECT: increase in the speed of information exchange under the influence of interference.
