Abstract :
Location finding searchers have recently emerged as essential elements in future CDMA wireless systems. In this paper we present a new combined architecture for location searchers and conventional RAKE receivers, which is based on multiplexing common hardware blocks between the two structures. In so doing, most of the needed hardware for the conventional RAKE fingers and channel searcher is saved with no performance degradation. Furthermore, the new architecture can avoid the need to use delay locked loops
