<p>PROBLEM TO BE SOLVED: To provide a reception synchronization device that can quickly state data communication by shortening a processing time required for the synchronization. SOLUTION: A searcher/finger circuit (reception synchronization circuit) [k] (k=1, 2, 3, or 4) is provided with a searcher/finger section acting like a searcher circuit that searches an object of a phase for inverse spread demodulation synchronously with a phase of a spread modulation signal from a received signal including the spread modulation signal in a search mode and acting like a finger circuit that tries synchronization according to the searched phase to demodulate the spread modulation signal in a finger mode and with a mode setting section that selects the search mode or the finger mode for the operating mode of the searcher/finger section on the basis of the search result in the search mode, and the selection of the operating mode is automatically conducted in the inside of the reception synchronization circuit [k].</p> |
