ABSTRACT:
A method of recovering transmitted symbols in a receiver of a spread spectrum system, comprising: receiving a signal including multi-path components associated with transmitted symbols; de-spreading successive separate portions of the received signal to provide a symbol estimate based on each multipath component, wherein the de-spreading step comprises determining at least one partial estimate of at least one transmitted symbol for an at least one partial multi-path component contained in a separate portion; and summing the partial estimates of separate portions corresponding to a same transmitted symbol.
