SYSTEM OCH FOERFARANDE FOER BERAEKNING AV EN KOMMUNIKATIONSKANALS KANALFOERSTAERKNING OCH BRUSVARIANS

摘要

A system and method for correcting for Rayleigh interference of a signal transmitted upon a multi-path channel. The system adaptively calculates values of channel gain and noise variance of the channel upon which the signal is transmitted, and generates signals indicative of such calculations which are supplied to a decoder. The system may be utilized to form a portion of a coherent, or noncoherent receiver which receives encoded and differentially-encoded signals.
