A performance analysis of Trellis Coded Modulation for OFDM systems in the Wireless Communications Environments
무선 통신 환경에서 OFDM 시스템을 위한 트렐리스 부호화 방식의 성능분석
Abstract
In this paper, we propose a robust trellis coded OFDM(orthogonal frequency division multiplexing) system for wireless communications over frequency selective fading channels. Computer simulations show that the proposed system achieves the better frame error rate(FER) performance as compared with the conventional Space time coded OFDM system in the correlated channel with multiple transmitter antennas.
