Abstract
In this paper, we analysis the error performance improvement of the FS MC-CDMA, whose information data are spread spectrum with direct sequences(DS), and each subband signal is transmitted using a subcarrier frequency, combining BCH code in Mobile communication channels which is characterized by Nakagami fading. The effect of co-channel interference on the block error performance is also studied in this paper. As a results of study, the coding techniques provides more efficient improvement than non-coding, but the coding techniques are required more band as many coding rate. Our study demonstrates that the system is combined coding techniques, the amount of improvement is capable of efficiently exploiting over the Nakagami fading.
본 논문에서는 DS-CDMA 시스템 구현 시 복잡성을 감소시키는 다중접속간섭 등의 여러 감쇠 요인을 고려하여 이를 개선시킬 수 있는 FS MC-CDMA 시스템의 성능을 분석하고 열악한 무선 모바일 환경에서 성능 개선기법인 BCH 부호화기법을 채용하여 FS MC-CDMA 시스템의 성능을 개선하였다. 또한 차세대 무선 모바일 통신 채널 환경으로는 나카가미 페이딩을 적용하여 FS MC-CDMA 시스템의 성능을 분석하여 검토하였다.
