We considered the issues of quasi-optimal signal processing with the correlated non-Gaussian narrowband noise on the background. It is shown that introducing a demodulator of blocks in the block diagram, where processing is carried out by instantaneous values and by the envelope of influencing non-Gaussian noise which range is comparable or narrower than the range of the processed signal, can improve the quality of demodulation in comparison with the demodulator, where processing is carried out only by the envelope or the instantaneous values of band-pass non-Gaussian additive noise.
