There is provided a CDMA receiver and a reception method in which even in the case where a reception timing of a radio frame becomes earlier than a reception reference timing of a base station at the time of DHO, flexible follow-up to a mobile station can be carried out, and continuous reception is enabled without complicating an instrumental structure. In the CDMA receiver comprising a radio circuit portion (40) for obtaining a base band signal (11) from a high frequency signal received by an antenna (41) and a demodulation circuit portion (10A) for combining signals from a plurality of paths contained in the base band signal to obtain a demodulated signal, a searcher (13A) of the demodulation circuit portion is constructed by including a search window offset delay circuit (24) supplied with an output of a spreading code generator (25) to supply the output to a search delay circuit (23), and a search window offset control portion (26) for controlling the search window offset delay circuit, and further, a selector (32) connected to a control output from the search window offset control portion and a diversity handover start signal line (17) from the receiver control portion (19) and having an output connected to the search window offset delay circuit. By this, a timing for starting a search is formed to be capable of being changed. <IMAGE> |
