The RAKE reception apparatus includes a searcher adapted for retrieving respective path timings for multi-path spread-spectrum signals received signals, a plurality of finger circuits (1,6,7,8) for despreading and demodulating the spread-spectrum signals found by said searcher, and a RAKE combiner (2) for combining outputs of the plural finger circuits. The plurality of finger circuits do not each contain a DLL circuit. Instead, there is one DLL circuit (5) provided for a plurality of finger circuits. The finger circuit to be tracked by the single DLL circuit is selected by a changeover circuit (4). A control circuit (3) is provided for controlling the changeover circuit based on the weighting information for each finger circuit obtained by the RAKE combiner. The said control circuit sequentially selects the optimal finger circuit to be tracked by the DLL circuit. <IMAGE> |
