This is a proposal by the Program in Applied and ComputationalMathematics at Princeton University and the Electrical Engineering Department at UT Dallas aimed at demonstrating the value of algebraic structure to cross layer design of multiple antenna wireless communication systems. At the network layer it develops techniques for multiple access (many to one) and broadcast (one to many) communication where algebraic structure enables very simple implementation. Adaptive and non-coherent techniques will be used at the physical layer to design receiver architectures that are robust under mobility, and where the end to end complexity of signal processing is comparable to that of single antenna systems. Algebraic structure will make it possible to integrate these different functions very efficiently. The focus at the network layer is to combine high rates with high reliability through innovation in coding and signal processing. Multiple access will be supported by using exotic algebraic structures such as Cayley Numbers to design new methods for interference cancellation. Broadcast applications (fixed and mobile) will be supported through a new type of code that is designed to achieve high rate, but has embedded within it a higher diversity (lower rate) code. This departs from standard practice which is to sacrifice diversity to achieve high rate and vice versa. Another important theme is the emphasis on measuring the value of innovation at the physical layer in terms of throughput, latency, or utility at the application layer. The research activities in this proposal have attracted strong interest from telecommunications infrastructure companies, including some with R&D facilities in the Dallas area. The proposal builds on a substantive collaboration between Calderbank and Al-Dhahir with a history of standards impact on both CDMA and GSM. The emphasis on expressing the value of algebraic structure to emerging broadband wireless standards creates a common language for discussion with industrial partners. Familiarity with these standards will advantage graduate students when they apply for internships and it is expected they will be able to jump into projects and make an immediate contribution. The value of integrating channel estimation, decoding and equalization and of integrating applications and physical layer innovation will be expressed in simulations that can be shared with industrial partners and academic collaborators. Students may also implement signal processing algorithms developed for this project in a new MIMO wireless testbed at UT Dallas. These initiatives will reduce the barrier to adoption and promote curiosity about the power of mathematics. Research across traditional domain boundaries will increase the pool of students who appreciate the power of mathematics and the important role that it plays in engineering and many of the sciences. It will encourage interdisciplinary exploration and breadth, and it will train students so that they can flourish in the different cultures associated with different academic disciplines. The ability to bridge different worlds is a quality that is increasingly important to success in both academic and non-academic careers.

这是该计划在普林斯顿大学的应用和计算仪式方面的一项建议，以及UT达拉斯的电气工程系，旨在证明代数结构对多个天线无线通信系统的跨层设计的价值。在网络层上，它开发了用于多个访问（许多比一）的技术，并广播（一对一）通信，代数结构可以实现非常简单的实现。自适应和非连锁技术将在物理层使用，以设计在迁移率下可靠的接收器体系结构，并且信号处理的端到端复杂性与单个天线系统的端到端复杂性相当。代数结构将非常有效地集成这些不同的功能是可能的。网络层的重点是通过编码和信号处理中的创新将高率与高可靠性相结合。通过使用异国情调的代数结构（例如Cayley编号）设计新方法进行干扰取消，将支持多个访问。广播应用程序（固定和移动）将通过一种新型代码来支持，该代码旨在达到高率，但嵌入了更高的多样性（较低率）代码。这与标准实践不同，即牺牲多样性以实现高率，反之亦然。另一个重要的主题是强调以应用层的吞吐量，延迟或实用程序来衡量物理层的创新价值。该提案中的研究活动引起了电信基础设施公司的浓厚兴趣，其中包括达拉斯地区的研发设施。该提案建立在Calderbank和Al-Dhahir之间的实质性合作基础上，具有标准史对CDMA和GSM的影响。强调表达代数结构对新兴宽带无线标准的价值创造了一种与工业伙伴讨论的共同语言。熟悉这些标准的研究生在申请实习时会优势，预计他们将能够跳入项目并立即做出贡献。集成渠道估计，解码和均衡以及集成应用程序和物理层创新的价值将在可以与工业合作伙伴和学术合作者共享的模拟中表达。学生还可以在UT Dallas的新的MIMO无线测试床上实施为该项目开发的信号处理算法。这些举措将减少采用的障碍，并促进对数学力量的好奇心。跨传统领域边界的研究将增加欣赏数学力量以及其在工程和许多科学中所发挥的重要作用的学生。它将鼓励跨学科的探索和广度，并将培训学生，以便他们可以在与不同学科相关的不同文化中繁荣发展。弥合不同世界的能力是一种对在学术和非学术职业中的成功越来越重要的品质。
