“…However, an arbitrary variation in the carrier frequency of one of the signals, including that due to the Doppler effect, within the framework of the conventional approach without compensation for the unknown frequency shift leads to that the efficiency of the correlation methods significantly decreases. The signal-processing methods, which are based on calculating and analyzing the uncertainty function [1][2][3][4][5], as well as the correlational processing of the results of adaptive digital filtering of the harmonic filling of the signals [6,7], are widely used in such problems related to estimating the mutual frequency-time characteristics of the signals. Due to the fact that the scaling factor in Eq.…”

We consider a modification of the method for determining the mutual time delays of signals on the basis of the joint measurement of the time and frequency shifts. The modification allows one to increase the degree of manifestation of the correlation maximum for the frequency-modulated signals. The results of studying the proposed algorithm during processing of the phase-and frequency-modulated signals under the conditions of a priori uncertainty with respect to the carrier frequency of the signals are presented.

The purpose of this paper is to synthesize an algorithm for coherent digital demodulation of non-uniformly distributed radio signals with absolute two-position phase shift keying, which has a small computational complexity, and to develop a miniature low-power demodulator on its basis. The relevance of the study is determined by the absence of similar devices in the Russian radio electronic market. The algorithm is based on digital phase-locked-loop frequency control. Its basic idea is to retain the optimal amplitude ratio between the phase quadrature of the received signal using a proportional-integral- differential controller. A digital device with the stated technical characteristics was obtained as a result of the study.
