A Comparisons of TCM schemes for OFDM in fading channel

페이딩 채널에서 OFDM에 적용 가능한 TCM방식 비교분석

In this paper, it was studied that the performance of OFDM transmission scheme was improved in fading channel by applying TCM, which has advantages of error correction and bandwidth efficiency. Simulation was carried out for two TCM models with different code efficient length. By mapping two models to square 16QAM, the model with the code efficient length of 2 achieved 3㏈ better than the other for the BER of 10$^{-3}$ . In conclusion, if we want to achieve a better performance with TCM in OFDM applications, we should select a TCM with langer code efficient length.
