COMMUNICATION EQUIPMENT AND METHOD FOR SUPPRESSING INTERFERENCE BY USING ADAPTIVE EQUALIZATION IN SPREAD SPECTRUM COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide the improved interference suppression method for a DS- CDMA system. ;SOLUTION: This communication equipment of a mobile station or the like for a spread spectrum communication system which is provided with a receiver 100 provided with an adaptive equalizer 104 for suppressing interference on received spread spectrum signals and generating equalized signals 126. A pilot channel demodulator 110 demodulates the equalized signals and generates the estimated value 140 of a pilot channel. An adder 112 compares the pilot channel estimated value with a prescribed data pattern and generates error signals 124. A traffic channel demodulator 108 demodulates the equalized signals and generates one or more traffic channels.;COPYRIGHT: (C)1999,JPO
