A CDMA receiver in which a searcher searches paths, fingers de-spread received signals and demodulate data for the searched paths, and a combiner combines output data of the fingers according to levels of the received signals. Furthermore, gain amplifiers that designate weights for respective paths

A CDMA receiver in which a searcher searches paths, fingers de-spread received signals and demodulate data for the searched paths, and a combiner combines output data of the fingers according to levels of the received signals. Furthermore, gain amplifiers that designate weights for respective paths are included in the combiner and signal intensities of demodulated data through the respective paths are detected. The gain amplifiers designate weights for the respective paths in such a manner that larger weights are designated to paths with larger signal intensities.

1. A receiving unit for receiving a signal spectrum-spread with a spread code, comprising:a searcher for searching a plurality of paths of a respective plurality of signals; a plurality of fingers for de-spreading said plurality of signals respectively transmitted along said plurality of paths searched by said searcher, for demodulating data, and for detecting a respective plurality of levels of said plurality of signals; first combining means for combining first output data of said plurality of fingers according to said plurality of levels of said plurality of signals and for generating a data signal; second combining means for combining second output data of said plurality of fingers and for generating a control signal; and gain control means for receiving said data signal output from said first combining means and for controlling a gain of said gain control means according to said control signal output from said second combining means so that a signal level of received data is constant.
