Wireless Video Transmission Based on Distributed Source Coding Principles

分布式信源编码（DSC）由于其巨大的应用潜力，近年来成为一个非常活跃的研究领域。然而，大多数得到的结果仍然停留在理论水平。因此，DSC的研究成果与实际应用之间还有很大的差距。因此，当今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依赖性的有用信息，并且因此不能实现理论所承诺的显著性能增益。该项目的最终目标是弥合理论与实践之间的差距，解决DSC核心的关键问题，并以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，深空通信和异构无线有线网络上的商业实时视频组播等应用。实用的信源信道编码方案将根据DSC原理设计。

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.
