Performance of video transport over wireless networks using hybrid ARQ

The advances in low bit rate video coding technology have led to the possibility of delivering video services to users through band-limited wireless networks. The paper proposes a hybrid ARQ error control scheme based on the concatenation of a Reed-Solomon (RS) code and a rate-compatible punctured convolutional (RCPC) code. The performance of the proposed hybrid ARQ scheme is simulated and compared with that of conventional hybrid ARQ schemes for real-time H.263 video transmission over wireless networks.
