| 1. A base station comprising a receiver and transmitter, the receiver including:
an antenna configured to receive a communication signal, the communication signal including a plurality of individual channels;
an adaptive matched filter configured to filter the received signal and generate a filtered signal using a weighting signal;
an analyzer configured to analyze the received signal for errors and generate a correction signal based on the analysis, the
analyzer further including:
at least one despreader configured to despread said filtered signal using a pilot signal, and provide a despread filtered
signal;
a processor configured to perform a hard decision on the despread filtered signal and generate symbol outputs therefrom; and
an error correction generator circuit configured to generate the correction signal; and
a correction unit configured to correct the received signal at a symbol level by using the correction signal, whereby the
correction of the received signal removes a phase error from the despread filtered signal.
