Abstract

Introduction. The synthesis procedure of coherent-incoherent demodulation of digital signals with binary frequency modulation (F3E-2) is the basic and the purpose of this article. Synthesis procedure method of coherent-incoherent demodulation of useful signal with F3E-2 which is observed with a powerful and alike hindrance with F3E-2. Coherent reception of similar hindrance with F3E-2 and incoherent reception of useful digital signal with F3E-2 in a channel with additive white noise are showed. Simplifying transformations of coherent-incoherent demodulation procedure of useful digital signal with F3E-2 in the conditions of similar powerful hindrance. Simplification of procedure of coherent-incoherent demodulations of digital signals with F3E-2 is accomplished. Conclusions. In absence of hindrance this procedure degenerates in classic incoherent demodulation of digital signal with F3E-2. This procedure can be used for programs realization of the repeated use of frequency resource and in development of perspective protection from hindrances of radio contact facilities.
