Iterative Decoding for Uncompressed Wireless Video Transmission

Due to the emergence of mm Wave systems that provide multi-Gbps data rate over 60GHz band, uncompressed video transmission has been considered as a commonly used feature for wireless multimedia transmission over the wireless personal area networks (WPANs). However, mm Waves signals usually have higher attenuation than the conventional low-frequency wireless signals, and therefore supporting transmission in a low SNR condition becomes a challenging problem for such systems. In this paper, we propose a iterative decoding method for the wireless transmission of uncompressed video. With our proposed iterative decoding structure, the video decoder utilizes the temporal redundancy among the video frames to jointly decode the received coded bits from different video frames with the aid of correlation noise model. The simulation results show that the proposed method can significantly enhanced the video quality in terms of PSNR, even while operating in an extremely low SNR condition.
