Analysis of achievements in the sphere of digital signal processing in application to the conditions when useful digital signal, white noise and interfering digital signal similar to the useful one, which significantly exceeds the latter in simultaneous power, are present in the communications channel is performed. It is shown that under such conditions highly effective processing of useful signal is possible and the potential interference immunity of the useful signal demodulation is equal to the interference immunity in the channel with the white noise only, i.e. in the absence of the interfering signal.
