ABSTRACT:
The invention discloses a cell search method for a CDMA system for a three-stage cell search procedure. The cell search method have the steps of matching incoming signals; over-sampling the incoming signals N times against a chip rate; down-sampling the incoming signals and outputting N over-samples (Y1(k), Y2(k),YN(k)) to N parallel signal paths; choosing randomly a sample of the N over-samples; and transmitting the sample chosen randomly from the N over-samples into a first stage process, a second stage process and a third stage process to accomplish a trial. The invention significantly reduces the effect of clock offset so as to accomplish fast cell search.
