Abstract: The present invention relates to a receiver for receiving at least one of a plurality of channels in a communication system, the receiver comprising: an adaptive matched filter (79) for receiving communication signals and producing a filtered signal by using a weighting signal; a rake receiver (101) for receiving communication signals and a pseudo-noise signal (931) generated for a selected channel and producing a filter weighting signal; means for defining the filter weighting signal with a correction signal (119), said correction signal to produce the weighting signal used by said adaptive matched filter; a channel despreader (85) for said selected channel coupled to said adaptive matched filter output for despreading said filtered signal using the pseudo-noise signal generated for said selected channel to produce a despread channel signal (95) of said selected channel; a pilot channel despreader (87) for a pilot channel coupled to said adaptive matched filter output for despreading said filtered signal using a pseudo-noise signal generated for said pilot channel to produce a despread pilot signal (135) of said pilot channel; a hard decision processor (121) in association with a complex conjugate processor (123) for receiving the despread channel signal of said selected channel and producing said correction signal; and means (157) for producing a phase correction signal (183) utilizing at least said despread pilot signal, said phase correction signal being applied to produce phase-corrected channel signals.
