Abstract
A wireless receiver (UST). The receiver comprises at least one antenna (ATU) for receiving a plurality of frames (FR) in a form of a plurality of paths. Each of the plurality of frames comprises a plurality of time slots (SL.sub.N), and each of the plurality of time slots comprises a plurality of symbols. Further, each of the plurality of paths has a corresponding sample position, wherein the plurality of symbols comprise a primary synchronization code symbol (PSC). The receiver further comprises circuitry (52) for correlating a primary synchronization code across a group of the plurality of symbols, and circuitry for identifying a plurality of path positions within the group. Each of the plurality of path positions corresponds to a respective one of a plurality of largest-amplitude paths represented within the group as detected in response to the circuitry for correlating. Finally, the receiver comprises circuitry for combining (54, 58) the plurality of largest-amplitude paths in response to identification of those paths by the circuitry for identifying.
