The synthesis method of the incoherent demodulation procedure of two synchronous mutually non-orthogonal digital signals with frequency modulation is considered. In the absence of interference this procedure degenerates into the procedure of classical incoherent demodulation of a digital signal with frequency modulation. When the instantaneous power of one of the signals significantly exceeds the instantaneous power of the other, the interference immunity of the latter approaches the immunity of reception in a channel with additive white Gaussian noise without interference. This procedure can be used in the development of modem compensators that ensure repeated use of the frequency resource as well as in the development of promising interference-protected radio communication devices.Downloads
