Optimal solution for SVC-based video transmission over a realistic mimo channel using precoder designs

摘要

In this paper we propose a novel scheme for SVC-based video transmission over MIMO channels using precoder solutions. On the one hand, H.264/SVC codec ensures spatial, temporal and quality scalabilities and provides an intrinsic hierarchy over transmitted bitstreams. On the other hand, precoder designs, which decouple a MIMO channel into parallel and independent SISOsub-channels, offer a high BER performance with a hierarchy over the sub-channels. The proposed scheme exploits the scalability of the H.264/SVC codec jointly with four precoder solutions providing an UEP without any surplus redundancy. Besides, some of these precoders such as QoS and E-d
