Coding and System Design for Wireless Cooperative Relaying

目的：该计划的目标是建立在合作通信的理论基础上，并开发通信系统的关键组件，使这种系统在实践中。 特别是，我们的目标是调查的源终端和多个中继之间的合作技术，以增加在WLAN和蜂窝系统的上下文中的上行链路的容量的详细实现。 智力优点：该计划的智力价值是理论基础的发展，必要的系统设计原则，以及合作无线系统的原型系统的演示，这将使未来的无线通信容量扩展。该系统的目标是实现无线系统中的吞吐量增益，该吞吐量增益随着系统中单跳中继的数量而增加，同时在每个中继处保持低复杂度操作。 目标系统将在一个可配置的无线电平台上进行设计和评估。 更广泛的影响：更广泛的影响包括网络的发展，以满足国家宽带计划中概述的廉价无线宽带接入的愿景。通过我们的工业关系，开发的技术将从理论转化为商业实践，同时为相应的监管和标准化变革提供手段。新一代工程师将接受教育，能够设想，分析和开发未来的实用无线通信系统。为了扩大影响，我们的工作的实际应用将被纳入研究生课程和推广到代表性不足的群体。

Objective: The objective of this program is to build on the theoretical foundations of cooperative communications, and to develop key components of a communications system that would enable such a system in practice. In particular, the goal is to investigate the detailed implementation of a cooperation technique between the source terminal and multiple relays to increase the capacity of an uplink in the context of WLAN and cellular systems. Intellectual merit: The intellectual merit of this program is the development of the theoretical foundation, the necessary system design principles, and the demonstration of a prototype system of cooperative wireless systems that will enable future capacity scaling of wireless communications. The goal of this system will be to achieve a throughput gain in wireless systems that increases with the number of single-hop relays in the system, while maintaining low-complexity operations at each of the relays. The target system will be designed and evaluated on a configurable radio platform. Broader impacts: The broader impacts include the development of networks that meet the vision of inexpensive wireless broadband access everywhere as outlined in the National Broadband Plan. Through our industrial relations, the developed technology will be transformed from theory toward a commercial practice, simultaneously providing means for corresponding regulatory and standardization changes. A new generation of engineers will be educated, able to envision, analyze and develop practical wireless communications systems of the future. To broaden the impact, practical applications of our work will be incorporated in graduate curricula and outreach to underrepresented groups.
