Abstract
A CDMA receiver wherein power consumption can be reduced by conducting receiving operation according to the kind of receiving data is provided. The CDMA receiver obtains a CDMA signal by executing RAKE combination to outputs from a plurality of finger sections in a RAKE combining section. A CPU detects a parameter indicating the kind of transmitting data from the signal after the RAKE combination to control the number of finger sections to be activated according to the detected kind of data. Moreover, a searcher section selects finger sections in the number specified by the CPU so that a timing generating section can supply clock signals to only the selected finger sections. Thereby, it becomes possible to activate finger sections in the number according to the kind of data, thus enabling the power consumption to be reduced.
