CAREER: Information Theory and Coding for Wireless Broadcast Networks

“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。职业：无线广播网络的信息理论和编码广播是无线通信的基本性质。利用适当的编码架构，无线通信的广播性质可以被用于以高速率同时向多个接收器发送的优点。以前的大部分工作集中在以下两个场景：1）向每个接收者发送相同的消息; 2）向不同的接收者发送完全不同的消息。在这两个之间？极端？广播场景，有丰富的集合？中级？有趣的配置和重大工程上诉的消息集的问题。了解的限制和适当的编码架构的广播网络与一般的消息集配置是一个相对未开发的挑战，必须加以解决，以充分利用无线communication.This研究的广播优势需要一个基本的信息理论的观点，广播网络的洞察到什么样的编码架构是适合于不同的消息集配置。这项研究的一个重要组成部分是专注于具体和物理动机的无线网络通信模型。特别感兴趣的是了解多输入多输出（MIMO）通信的影响。具体而言，本研究研究：1）消息集配置对无线广播网络的适当编码架构的影响; 2）物理激励模型下的保密通信;以及3）广播网络通信的接收方消息侧信息的价值。该研究计划是由教育工作的补充，以培养下一代工程师成为熟练的无线网络设计，其中包括开发一个新的无线系统信息理论课程，并编写一个伴随的教科书。

"This award is funded under the American Recovery and Reinvestment Act of 2009(Public Law 111-5)."CAREER: Information Theory and Coding for Wireless Broadcast NetworksBroadcast is a fundamental nature of wireless communication. With appropriate coding architecture, the broadcast nature of wireless communication can be used to the advantage of simultaneously transmitting to several receivers at high rates. Most of the previous work focused on the following two scenarios: 1) to deliver the same message to each of the receivers; 2) to deliver completely different messages to different receivers. Between these two ?extreme? broadcast scenarios, there is a rich collection of ?intermediate? problems with message sets of interesting configuration and significant engineering appeal. Understanding the limits and the appropriate coding architectures of broadcast networks with general message set configurations is a relatively unexplored challenge that must be addressed to fully harness the broadcast advantage of wireless communication.This research takes a fundamental information-theoretic view of broadcast networks to shed insight into what coding architectures are appropriate for different message set configurations. An important component of this study is the focus on concrete and physically motivated models of wireless network communication. Of particular interest is to understand the impact of multiple-input multiple-output (MIMO) communication. Specifically, this research studies: 1) the impact of message set configuration on the appropriate coding architecture of wireless broadcast networks; 2) secrecy communication under physically motivated models; and 3) the value of receiver message side information for broadcast network communication. The research program is complemented by an educational effort to train the next generation of engineers to become skilled in the design of wireless networks, which involves developing a new course on information theory for wireless systems and writing an accompanied textbook.
