Abstract

The present invention concerns a new type of rake receiver, namely, a multimode rake receiver, which may be included within either a mobile station or a base station, and which has dynamic pilot signal searching and multipath reception and combining capability, for CDMA, cdma2000, W-CDMA, or other mobile communication systems. The adaptive, multimode rake receiver includes a network interface, a plurality of adaptive multimode rake fingers, and a multimode processor. Each adaptive multimode rake finger and the multimode processor are responsive to first configuration information (a first mode signal) to configure for a path reception functional mode and are further responsive to second configuration information (a second mode signal) to configure for a searcher functional mode, providing the multimode rake receiver with acquisition, traffic, and idle modes. In the preferred embodiment, the multimode rake receiver is implemented using a new category of integrated circuitry for adaptive or reconfigurable computing, providing a plurality of heterogeneous computational elements coupled to an interconnection network, to form adaptive and reconfigurable multimode rake fingers and a multimode processor, for a plurality of different functional modes, including pilot signal searching and multipath reception and combination.
