Transmission of MPEG-2 Encoded VoD Services over Wireless Access Networks Using Type-II Hybrid ARQ Schemes with RCPC Codes

In this paper, we investigate the e ectiveness of applying type-II hybrid ARQ schemes to the transmission of MPEG-2 encoded video streams over xed wireless links in broadband xed 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 xed wireless channels are modeled by a speci c nite-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.
