1. A method of acquiring one or more pilots in a wireless communication system, comprising:

  • searching for peaks in a received signal over a designated code space to provide a set of one or more candidate peaks;

    processing each candidate peak to acquire the candidate peak;

    performing the searching and processing a plurality of times such that the searching for a next set of candidate peaks is performed in parallel with the processing for a current set of candidate peaks; and

    terminating the searching and processing early upon detection of pilot acquisition to reduce acquisition time, wherein the searching includes detecting peaks over the designated code space to provide a set of detected peaks, and re-evaluating each detected peak to remove noise peaks and provide the one or more candidate peaks.
