FIELD: radio engineering, possible use in radio navigation and radio communication systems for receiving noise-like frequency-manipulated signals with continuous phase. ^ SUBSTANCE: in accordance to the method, input signal is decomposed onto quadrature components separately for each one of two symbolic frequencies, quadrature components of signal are decoded, cophased and quadrature components of signal are combined in pairs by two frequency channels, cophased and quadrature components of mutual correlation function of received and synchronous supporting noise-like signals are composed by integrating results of conjugation of cophased and quadrature components of signal in two frequency channels on spectrum which is equal to duration of noise-like signal, with following extraction of information symbols on basis of detection of sign of cophased component of mutual correlation function. ^ EFFECT: increased interference resistance when receiving noise-like frequency-manipulated signals with continuous phase. ^ 3 dwg |
