INCOHERENT RECEIVER FREQUENCY-SHIFT KEYED SIGNAL WITH MINIMAL SHIFT

摘要

FIELD: communication facilities.;SUBSTANCE: invention relates to field of transmission of discrete and analog information in digital form and can be used at development of radio modulus of systems of vehicular radio communication. Established technical result is achieved by changing in each of channels known incoherent receiver FM-MC signals of generators with carrying oscillation cosω₀t and sinω₀t respectively to generators with carrying oscillations cos(πt/2T)cosω₀t and sin(πt/2T)sinω₀t, filters of lower frequencies to integrating elements with discharge, and also introduction of additionally two channels, subtractor and commutator.;EFFECT: providing of potential noise immunity of incoherent receiver of frequency-shift keyed signals with minimal shift (FM-MC signal) on the basis of implementation of optimal incoherent processing algorithm of the received signal.;1 dwg
