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.
