Abstract
We consider the detection of periodic pulse sequences and their suppression by compensation in the channel of information leakage. The objective is to find a periodic pulse sequence of additive noise of high level for its subsequent suppression. Detection is based on the fast Fourier transform and a priori information on the spectrum of the periodic pulse sequences. Comparison and evaluation of the detection is carried out with the best reception and the threshold detection. The choice of threshold is performed by well-known criteria of optimality in problems of signal detection. Suppression of pulse sequences in the channel of leak is solved by their compensation by playback of antiphase signal detection. Experiments were carried out by simulations of the periodic pulse sequence with the addition of the additive noise such as white noise, a chaotic pulse train, telegraph signal. The method of detection and compensation of noisy pulse sequences is suggested.
