Title
Distortion-aware joint scheduling and resource allocation for wireless video transmission
Abstract
The performance of Direct Sequence Code Division Multiple Access (DS-CDMA) based systems highly depends on the interference caused by multiple transmissions. Interference reduction may result by using time scheduling of the transmitting nodes and by allocating accordingly the power level, and the source and channel coding rate for each node. In this work, we study the joint intra-cell scheduling and resource allocation for wireless video transmission in a hybrid DS-CDMA over Time Division Multiple Access (TDMA) network. We examine the case according to which a subset of the network nodes are able to simultaneously transmit (at the same time slot). The key issue is to jointly select the subset of the nodes for transmission per time slot and to allocate the available resources so that a function of the end-to-end video distortion of each node over a time frame is minimized. The experimental results show that our proposed approach results in enhanced end-to-end video quality compared to a similar DS-CDMA system.
