Receiver and base station for producing phase-corrected channel signals
First Claim
1. A receiver for receiving at least one of a plurality of channels in a communication signal, the receiver comprising:
- (a) a hard decision processor in association with a complex conjugate processor for receiving a despread channel signal of a selected channel and producing a correction signal; and
(b) a phase-locked loop (PLL) configured to utilize a despread pilot signal of a pilot channel for producing a phase correction signal which is applied to produce phase-corrected channel signals.

Abstract
A receiver and base station for producing phase-corrected channel signals. An adaptive matched filter produces a filtered signal by using a weighting signal. A rake receiver produces a filter weighting signal using a pseudo-noise signal generator. A channel despreader despreads the filtered signal using the pseudo-noise signal generated to produce a despread channel signal of the selected channel. A pilot channel despreader despreads the filtered signal using a pseudo-noise signal generator to produce a despread pilot signal of the pilot channel. A hard decision processor receives the despread channel signal of the selected channel and produces a correction signal. A phase-locked loop utilizes at least the despread pilot signal and produces a phase correction signal which is applied to produce phase-corrected channel signals.
