METHOD FOR NOISELESS RECEPTION OF PHASE-MANIPULATED SIGNALS Russian patent published in 2009 - IPC H04B15/00 

Abstract RU 2359411 C2

FIELD: physics, radio.

SUBSTANCE: invention is related to the field of radio engineering, in particular, to methods of reception under condition of noise from pseudonoise phase-manipulated signals synthesised on the basis of pseudorandom code sequences used in radiolocating, radio-navigation systems and communication systems, which use code separation of access channels. Method for reception of phase-manipulated signals differs by the fact that counts of received and reference signals at the inlet of correlation receiver are preliminarily exposed to interlacing in compliance with rule of fractal reflection, which has chaotic dynamics. Interlacing is realised cyclically by Nmax clock pulses in every cycle. Then value of correlation integral is calculated, calculated value of correlation integral is compared to threshold, and decision is made on availability or unavailability of signal at the inlet of receiving device in compliance with specified criterion of detection.

EFFECT: increased sensitivity and noise immunity of receiving devices for phase-manipulated signals under effect of concentrated wideband imitating noises, harmonical and polyharmonical noises.
