Abstract
In this paper, we propose and analyze a multiuser receiver using a decorrelating filter and Viterbi decoders for trellis coded DS/CDMA systems with biorthgonal signal constellation in asynchronous channels. The biorthogonality is implemented by user signature waveforms and the decorrelating filter. The performance of the proposed system is investigated with emphasis on the asymptotic cases. It is shown that the proposed system can provide us with some coding gain and near-far resistance. We also analyze the performance of the proposed system with base-station antenna array.
이 논문에서는 비동기 채널에서 쌍직교 신호 별자리를 갖는 격자부호화 직접수열 부호분할 다중접속 시스템에 알맞도록 역상관 여파기와 비터비 복호기를 쓰는 여러쓰는이 수신기를 제안하고 그 성능을 분석한다. 쌍직교성은 쓰는이 서명파와 역상관 여파기로 구현한다. 제안한 시스템 성능의 점근 성능을 중점적으로 분석하였다. 제안한 시스템을 쓰면 부호 이득을 얻을 수 있고 원근 문제에 강하다는 것을 보인다. 또한, 제안한 시스템에 기지국 안테나 배열을 썼을 때 성능을 분석한다.
