摘要：
A searcher for a CDMA receiver apparatus includes a correlator obtaining a correlation value between a spreading code sequence and a spreading code sequence within a received signal, and a non-linear processor carrying out a non-linear conversion to convert one of the correlation value and a predetermined value indicative of the correlation value into correlation value information which has a data width smaller than that of the one of the correlation value and the predetermined value. The correlation value information is used to carry out a search process to search for a synchronizing timing with respect to the spreading code sequence within the received signal.
