In this paper, we study the performance of a combined linkand physical-layer approach for the downlink of a dynamic OFDM-FDMA transmission system delivering MPEG-4 video streams. The approach consists of three different mechanisms — queue management, resource allocation, and subcarrier assignment — which can be used separately as well as in combination. This cross-layer approach allows to utilize channel-related knowledge and semantic information of the streams’ packets. Consecutively adding… CONTINUE READING
