Abstract:
A communication system including a receiver for receiving at least one of a plurality of channels in a communication signal, the receiver comprising:an adaptive matched filter for receiving communication signals producing a filtered signal by using a weighting signal; a rake receiver for receiving the communication signals and a pseudo-noise signal generated for a selected channel and producing a filter weighting signal; means for defining the filter weighting signal with a correction signal, said correction signal to produce the weighting signal used by said adaptive matched filter; a channel despreader 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 of said selected channel; a pilot channel despreader for a pilot channel coupled to said adaptive matched filter output for despreading said filtered signal using a pseudo-noise signal generator for said pilot channel to produce a despread pilot signal of said pilot channel; a hard decision processor in association with a complex conjugate processor for receiving the despread channel signal of said selected channel and producing said correction signal; and a phase-locked loop utilizing at least said despread pilot signal for producing a phase correction signal which is applied to produce phase-corrected channel signals.
