Abstract:
A radio communication system including a transmitter and a receiver, said receiver comprising:a plurality of diversity antennas;a plurality of signal distortion compensators for compensating distortion of incoming signals, respectively derived from said plurality of diversity antennas, by correlating each of said incoming signals with a reference signal;band-pass filter means, coupled to receive at least one of said incoming signals, for extracting pilot information inserted into a data signal radiated from said transmitter, said pilot information being generated using a carrier in said transmitter and having a level higher than a level of said data signal;reference signal generating means, coupled to receive an output of said band-pass filter means, for generating said reference signal after implementing gain control on said pilot information, said reference signal being applied to said plurality of signal distortion compensators;a maximum-ratio combiner, coupled to receive outputs of said plurality of signal distortion compensators, for improving a signal-to-noise ratio of a desired incoming signal; andmeans, coupled to said maximum-ratio combiner, for removing said pilot information.
