Patent ID: 7526014

Claim:
In a spread spectrum receiver capable of receiving signals from a plurality of transmitters, an apparatus comprising: a buffer for storing said received signals and generating parallel reception data associated with said received signals; a channel searcher for processing said parallel reception data in a parallel format and determining whether any of said plurality of transmitters is found in a position-division manner; and a plurality of channel trackers for processing said parallel reception data in said parallel format and tracking said found transmitter in a channel-division manner after said channel searcher finds at least one of said plurality of transmitters, wherein said channel searcher comprises: a code generator for generating a set of identification codes associated with one of said plurality of transmitters and providing N-bit parallel code data; a plurality of search engines for processing said N-bit parallel code data in said position-division manner and providing a plurality of correlation results; and a detector for determining whether said set of identification codes is correspondent with said received signals in response to said plurality of correlation results.
