Abstract:
A base station for transmitting and receiving communication signals, comprising a receiver and transmitter, for reducing transmission errors in said transmitted signal, the receiver including:an antenna for receiving a communication signal; an adaptive matched filter for filtering said received signal to generate a filtered signal using a weighting signal; an analyzer for analyzing said received signal for errors and generating a correction signal based on said analysis, and said analyzer further includes: at least one despreader for despreading said filtered signal using a pilot signal; a processor for performing a hard decision on said despread filtered signal and generating symbol outputs therefrom; and a conjugator for determining the complex conjugates of said symbol outputs to generate said correction signal; a correction unit for correcting said received signal using said correction signal; and whereby said transmitter is responsive to said correction unit, for correcting said transmitted signal prior to transmission.
