Base station which uses pre-rotation before transmission

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.
