| 摘要 |
The present invention is a user equipment for carrier offset recovery during reception of a communication signal over an air interface using a plurality of channels in a pilot signal. The user equipment comprises an adaptive match filter for producing a filtered signal using a weighting signal, a rake receiver for producing a filter weighting signal, and a means for defining the filter weighting signal with a correction signal. A channel despreader is also included in the user equipment for despreading the filtered signal using a pseudo-noise signal for a selected channel to produce a despread channel signal of the selected channel. A pilot channel despreader is coupled to the adaptive match filter output for despreading the filter signal using a pseudo-noise signal generated for the pilot channel, producing a despread pilot signal of the pilot channel. A hard decision processor, associated with a complex conjugate processor, is also included in the user equipment for producing the correction signal. A phase lock loop, which uses the despread pilot signal, produces a phase correction signal, which is applied to produce phase corrected channel signals.
