Abstract
A rake finger receiver and control method therefor, for use in a wireless spread communication system. The rake finger receiver includes a multiplexer, a searcher, a first switch fabric, a rake fingers and tracking pool, a second switch fabric, a combiner, a decoder, a channel estimator, and a rake finger controller. One searcher is used to serve multiple antennas of a base station so as to reduce the system complexity. The number of the rake fingers assigned for processing multipath components associated with a radio link is determined dynamically. Thus, the resource is utilized efficiently.
