An Adaptive Cross Layer Unequal Protection Method for Video Transmission over Wireless Communication Channels

摘要

In this paper, a new scheme, called Adaptive Cross Layer Unequal Protection (ACLUEP), has been proposed for video transmission over wireless channels. The proposed scheme performs joint optimization across application layer, link layer and physical layer to provide unequal protection ability for video bit-streams with different priority levels. Analysis and simulation results show an extraordinary improvement in Peak Signall-to-Noise Ratio (PSNR) of the proposed method over a variety of channel conditions.
