Transmission of MPEG-2 encoded VoD services over wireless access networks using type-II hybrid ARQ schemes with RCPC codes
HICSS（2000）
摘要
In this paper, we investigate the effectiveness of applying type-II hybrid ARQ schemes to the transmission of MPEG-2 encoded video streams over fixed wireless links in broadband fixed wireless access networks (B-FWANs) for video-on-demand (VoD) services. Rate compatible punctured convolutional (RCPC) codes are used. Simulations were conducted to evaluate the overall system performance. The fixed wireless channels are modeled by a specific finite-state Markov model in conjunction with the K-factor Rician fading model. Important metrics relevant to the broadband video services are analyzed including the error rate of the original information cells, the quality of the reconstructed video sequences, and channel throughput.
