Abstract

This research presents a robust video transmission scheme over fading wireless channels that relies on a coordinated protection effort in handling channel and source variations dynamically. Given the priority of each source packet and the estimated channel condition, an adaptive protection scheme based on joint source-channel criteria is investigated via proactive forward error correction (FEC). A product code is developed based on both the Reed-Solomon (RS) code and rate- compatible punctured convolutional (RCPC) codes. We explore the dynamic programming algorithm in matching the relative priority of source packets to instantaneous channel conditions. To obtain a realistic joint source-channel adaptation scheme, special attention has been paid to the channel status feedback in terms of accuracy and delay, the product code tradeoff, and the involved packetization efficiency. The performance improvement due to adaptation via a dynamic programming solution is demonstrated by simulating the wireless transmission of error resilient ITU-T H.263+ video.
