Patent ID: 7526012

Claim:
An interference reduction apparatus for diminishing an interference component contained in a despread signal obtained by despreading a spread-spectrum signal, comprising: peak detecting unit for calculating autocorrelation of a receive signal and detecting a signal peak; a multipath timing deciding unit for deciding timing of multipath from a base station with which communication is currently in progress; an interference-reducing timing decision unit for deciding an interference-reducing timing that is for diminishing an interference component arriving from an adjacent base station, using timing of said signal peak and the timing of said multipath; a despreading timing decision unit for deciding a plurality of despreading timings, at which despreading will be performed, based upon said interference-reducing timing and the timing of said multipath; a despreader for despreading the spread-spectrum signal at each of the despreading timings; and a combiner for RAKE-combining a plurality of results of despreading.
