radio engineering; code- division communication systems. SUBSTANCE: base-station correlator designed for correlation processing of signals from N subscribers functions to detect high-power signals of closest subscribers and to shape from them structural noise estimates. Structural noise estimates shaped in each channel are used to compensate for respective structural noise in input mixture by means of subtracter, one of subtracter inputs being supplied with input mixture through delay circuit and other one, with total estimates of structural noise shaped in each channel and passed through synchronous phase filter. EFFECT: enhanced structural noise immunity. 3 dwg |
