An adaptive cross-layer optimization scheme for light compressed high-definition video transmission based on 60 GHz system

By using 60GHz spectrum in high frequency carrier, IEEE 802.11ad is widely used in the transmission of high-definition videos. In this paper, an adaptive cross-layer optimization scheme is proposed based on IEEE 802.11ad which involves modulation and coding at the physical layer, retransmission policy at the medium access control layer and source coding at the video coding layer. The scheme aims at minimize the video distortion between original video at sending end and reconstructed video at receiver under certain time delay. Simulation results show that the proposed scheme can select a proper combination of parameters at each layer mentioned above for a given SNR and greatly improve the overall performance in minimizing the video distortion.
