联合信源信道编码方法的研究连续细化 * 源通过噪声信道的多播 * 用于媒体内容交付的无线多播预计将支持众多新兴的移动的应用，如移动的IPTV，电子广告，和移动的游戏，由于其一对多传输的性质是可扩展的接收器的数量。设想其重要性，建议DG计划研究一种新的框架编码无线多播，称为可伸缩源编码叠加编码（SSC-SPC），其目的是通过源和信道编码之间的智能映射创建多分辨率传输。具体来说，我们计划解决的问题，SSC-SPC组播在一些有趣的情况下，包括一个逻辑的SSC-SPC传输范例（称为SSC-L-SPC），使简单和标准兼容的设计在接收器，以及SSC-SPC组播在单和多中继网络中的解码和转发（DF），放大和转发（AF），非正交AF（NAF）的时尚，分别。它们被认为是文献中缺失的部分，对研究界来说很有趣。研究结果将有助于深入了解不同网络基础设施支持下的SSC-SPC传输性能，并为相关研究的发展做出贡献。* 根据拟议的研究课题，拟议的DG计划容纳了丰富的研究活动，参与的学生，包括两名博士生和一名暑期合作学生，将在网络架构设计，系统和问题制定，优化和案例研究/模拟方面接受充分的培训。他们不仅将学习学术研究技能，还将获得3GPP的多媒体广播多播服务（MBMS）和LTE中的多播广播单频网络（MBSFN）等行业标准化进展的知识。

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.**
