초록

DS-CDMA 다중 안테나 시스템에서 순방향 링크의 다중화를 위한 2차원 직교 가변 확산 부호를 제시하였다. 다중 사용자 환경 하에서의 AWGN 및 레일라이 페이딩 MIMO 채널을 위한 비트 오류율 성능을 평가하였다. 분석 결과로부터 제안 기법에 의한 유연한 부호율과 낮은 최대 상관값을 실현할 수 있음을 확인하였다.

Two-dimensional orthogonal variable spreading codes are presented far multiplexing of forward link in direct sequence code division multiple access(DS-CDMA) multiple antennas system. The bit error rate(BER) performance under a multi-user environment fur the additive white Gaussian noise(AWGN) channel and Rayleigh fading MIMO channel are evaluated. The results demonstrate that the proposed scheme could provide flexible rates and lower peak correlation values.
