Studies on joint source-channel coding approaches for multicast of successfully refined sources

用于媒体内容递送的联合信源-信道编码方法的研究*用于媒体内容递送的无线多播由于其一对多的传输本质上是可根据接收者的数量而扩展的，因此有望支持许多新兴的移动应用，例如移动IPTV、电子广告和移动游戏。考虑到其重要性，DG计划研究了一种新的编码无线组播框架，称为叠加编码上的可伸缩信源编码(SSC-SPC)，旨在通过信源和信道编码之间的智能映射来创建多分辨率传输。具体地说，我们计划在许多有趣的场景中解决SSC-SPC多播问题，包括逻辑SSC-SPC传输范例(称为SSC-L-SPC)，它允许在接收器进行简单和标准的兼容设计，以及分别以解码转发(DF)、放大转发(AF)和非正交AF(NAF)方式在单中继网络和多中继网络上的SSC-SPC多播。它们被认为是文献中缺失的部分，研究界对此很感兴趣。本文的研究成果可望对SSC-SPC传输在各种网络基础设施支持下的性能有更深入的了解，并为相关研究的发展做出坚实的贡献。*根据拟议的研究课题，拟议的DG计划提供了丰富的研究活动，通过这些活动，参与的学生，包括两名博士生和一名暑期合作社学生，将在网络架构设计、系统和问题表达、优化以及案例研究/模拟方面接受足够的培训。他们不仅将学习学术研究技能，还将获得3GPP的多媒体广播组播业务(MBMS)和LTE的组播广播单频网(MBSFN)等行业标准化进程的知识。**

Studies on joint source-channel coding approaches for multicast of successively refined***sources via noisy channels***Wireless multicast for media content delivery is expected to support numerous emerging mobile applications, such as mobile IPTV, electronic advertisements, and mobile gaming, due to its one-to-many transmission in nature that is scalable to the number of receivers. Envisioning its importance, the proposed DG program investigates a novel framework of coded wireless multicast, called Scalable source coding over superposition coding (SSC-SPC), which aims to create multi-resolution transmissions via an intelligent mapping between the source and channel coding. Specifically, we plan to tackle the problems of SSC-SPC multicast in a number of interesting scenarios, including a logical SSC-SPC transmission paradigm (called SSC-L-SPC) that enables simple and standard compatible design at the receivers, as well as SSC-SPC multicast over single- and multi-relay networks in the decode-and-forward (DF), amplify-and-forward (AF), non-orthogonal AF (NAF) fashion, respectively. They are considered missing pieces in the literature and interesting to the research community. The research results are expected to gain deep understanding on the performance of the SSC-SPC transmissions under various network infrastructure supports and solidly contribute to the state-of-the-art of the related research. ***Based on the proposed research topics, the proposed DG program accommodates abundant research activities, by which the participated students, including constantly two PhD students and a summer co-op student, will receive sufficient training in terms of network architecture design, system and problem formulation, optimization, and case studies/simulation. They will not only learn the academic research skills, but also obtain knowledge on industry standardization progress such as Multimedia Broadcast Multicast Services (MBMS) of 3GPP and Multicast-broadcast single-frequency network (MBSFN) in LTE.**
