(An) analysis of the performance of a coded orthogonal frequency division mulitplexing system in time-varying multipath rayleigh fading channel시변 다중 경로 레일리 감쇄 채널에서 부호화된 직교 주파수 분할 다중 시스템의 성능 분석
In this thesis, we first analyze the influence of interference due to the time variation and delay spread of the mobile channel on an orthogonal frequency division multiplexing (OFDM) system. With the result, we obtain the bit error rate performance of the 16-QAM OFDM system. Second, we investigate the performance of the RS coded 16-QAM OFDM system when the number of subcarriers varies. In the investigation, we assume that the information transmission rate and the total bandwidth expansion due to coding, guard interval, and the number of subcarriers are fixed. Under this condition, it is observed that there are optimum numbers of subcarriers that minimize the RS symbol error probability for various channel states.
