Zhifeng He, Shiwen Mao · 2013
Cognitive radio (CR) has been recognized as an important technology for enhancing spectrum efficiency. While many dynamic spectrum access techniques are developed to better utilize the allocated spectrum, the massive unlicensed bandwidth in the 60GHz band also provides great potential for supporting new bandwidth intensive applications. In this paper, we investigate the problem of streaming uncompressed High Definition (HD) videos over 60GHz networks. We present a multiple description (MD) coding (MDC) technique based on Priority Encoding Transmission (PET) that exploits the different significance of the pixel bits, and an interleaving based transmission scheme to combat the bursty losses due to blockage. A nonlinear integer programming problem is formulated and solved for determining the optimal parameters. The proposed scheme is cognitive and adaptive to the dynamic 60GHz link conditions for enhanced video quality. The performance of the proposed scheme is validated with simulations.
