In satellite digital broadcasting and satellite internet, severe burst errors occur in the high-speed return channel from the satellite to mobiles. In this paper, we analyze the performance of the forward error correction (FEC) coding method in the Rayleigh fading return channel. We first investigate the channel model of Loo, LutB, Vucetic and Corazza. We then compare the performance of the convolutional, Reed-Solomon (RS), convolution-RS concatenation, and Turbo codes in rayleigh fading channel.

위성 디지털 방송이나 위성 인터넷에서는 위성에서 단말에 이르는 고속 리턴 채널 환경이 매우 나빠 연집오류가 심하게 생긴다. 이 논문에서는 리턴 채별이 레일리 확률 채널일 때, 앞 오류 고침 (forward error correction: FEC) 부호화 방식의 성능을 분석한다. 먼저, Loo, Lutz, Vucetic, Corazza의 채별 모형을 고찰하고, Rayleigh 페이딩 채널에서 길쌈 부호, 리드 솔로몬 부호, 길쌈-리드 솔로몬 연접 부호 터보 부호의 성능을 비교 분석한다.
