PROBLEM TO BE SOLVED: To provide a device for cutting down the scale of a receiving circuit and reducing the power consumption while keeping the following function of the phase jitter of a multipath transmission path. SOLUTION: In a RAKE receiving device which is equipped with a plurality of finger circuits for receiving the signal being diffused into spectra by diffusion codes and decoding signals by reversely diffusing each received signal being searched for with a searcher for searching individual paths from a received signal, becoming a multipath, and a RAKE synthesizer which synthesizes the output of the finger circuits, the finger circuits are all not provided with DLL circuits within themselves, and one DLL circuit is installed for the finger circuits, and the finger being the target of the tracking of synchronization by the DLL circuit is switched by switching circuit, and this receiver is equipped with a control circuit which controls the switching circuit, based on the grade information in every finger that the RAKE synthesizer seeks, and selects one by one the fingers that the DLL circuit should follow. |
