SYNTHESIZED DIVERSITY RADIO COMMUNICATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To reduce the occurrence of a code error and to improve communication quality by executing an effective synthesis diversity while being sufficiently followed up to high speed phasing. SOLUTION: Digital reception intermediate frequency signals outputted from reception circuits 21a-21d are delay-processed in delay correction circuit 22a-22d, are demodulated in demodulation circuits 23a-23d and the digital demodulation signals BSa-BSd of a base band are obtained. The digital demodulation signals BSa-BSAd of the base band are inputted to multiplication circuits 24a-24d. The multiplication circuits 24a-24d multiply the digital demodulation signals BSa-Bsd of the base band by weighting coefficients WKa-WKd generated in a weighting coefficient generation circuit 50 based on C/N detection signals CNSa-CNSd so as to execute weighting. The respective digital demodulation signal after weighting are added/synthesized in a digital addition circuit 30.
