Wireless Video Transmission Based on Distributed Source Coding Principles

分布式信源编码(DSC)由于其巨大的实用潜力，近年来已成为一个非常活跃的研究领域。然而，已有的结果大多停留在理论层面上。因此，DSC的研究成果与实际应用还有很大差距。因此，今天的通信系统不能利用关于网络中信号之间的拓扑结构或统计相关性的有用信息，从而不能实现理论上承诺的显著性能提升。该项目的最终目标是弥合理论和实践之间的差距，解决DSC核心的关键问题，并通过这种方式为其在新兴系统和服务中的应用奠定基础。特别是，该项目将专注于无线多终端网络上的视频传输，并针对视频监控网络、深空通信和异类无线有线网络上的商业实时视频组播等应用。将基于DSC原理设计实用的信源-信道编码方案。

Due to its great practical potentials, distributed source coding (DSC) has recently become a very active research area. However, most obtained results have remained at the theoretical level. Thus, there is still a huge gap between research achievements and practical employment of DSC. Consequently, today's communication systems cannot exploit useful information about the topological structure or statistical dependence between signals in the network, and thus cannot realize significant performance gains promised by theory. The ultimate goal of the project is to bridge the gap between theory and practice, to solve key problems at the very heart of DSC, and in this way set the stage for its application in emerging systems and services. In particular, the project will focus on video transmission over wireless multiterminal networks and target at applications such as video surveillance networks, deep-space communications, and commercial real-time video multicast over heterogeneous wireless-wireline networks. Practical source-channel coding schemes will be designed based on DSC principles.
