Interference reduction apparatus and method |
摘要 |
A autocorrelation peak detector ( 54 ) and a interference-reducing timing generator ( 55 ) decide interference-reducing timings tau±(tau<SUB>2</SUB>-tau<SUB>1</SUB>) for eliminating interference components that arrive from an adjacent base station, and a path searcher ( 53 ) decides the path timing tau of multipath from a base station with which communication is currently in progress. A despreading timing decision unit ( 56 ) decides a plurality of despreading timings tau, tau±(tau<SUB>2</SUB>-tau<SUB>1</SUB>) from the above-mentioned timings, fingers ( 57 <SUB>1 </SUB>to 57 <SUB>3</SUB>) despread a receive spread-spectrum signal at respective ones of the despreading timings, and a RAKE combiner ( 58 ) weights and combines a plurality of results of despreading to thereby diminish interference components.
