Abstract

In this paper, we composed orthogonal multi carrier FH/CDMA system using frequency hopping sequence. Considering hit possibilities by delayed other user's signals we searched the optimal number of user access carrier slots not to influence on performance deterioration with the variation of number of carrier slots according to the number of user access carrier slots. A]io, we evaluated the BER performance improvement due to TCM and Concatenated coding technique by computer simulation.

본 논문에서는 주파수 도약 시퀀스를 사용하는 직교 멀티캐리어 FH/CDMA 시스템을 구성해 보고 지연된 다른 사용자 신호들에 의한 충돌 발생 가능성을 사용자 접속 캐리어 슬롯 수에 따라 변화시켜 가면서 성능 저하에 큰 영향을 미치지 않는 최적의 사용자 접속 캐리어 슬롯 수를 찾아보았다. 아울러 시스템의 TCM과 Concatenated code 기법을 적용하여 BER 성능 개선 정도를 컴퓨터 시뮬레이션을 통해 평가하였다.
