Efficient MIMO Transceivers Based on Channel Decomposition Techniques

摘要ECS-0621879 L。该提案的目标是为多输入多输出（MIMO）信道开发新的分解技术，并设计高效的MIMO收发器。过去，MIMO收发器设计一直依赖于奇异值分解（SVD）或QR分解来将MIMO信道转换为具有极大不同增益的并行标量信道。这要么导致比特加载策略，要么需要在信道吞吐量和系统错误性能之间进行持久的权衡。为了实现这一目标，研究人员提出了一种理论和实验相结合的方法，包括：1）建立基于新的信道分解范式的灵活、鲁棒的MIMO收发机设计理论; 2）将理论概括为解释各种级别的信道状态信息; 3）优化和调整MIMO收发器以用于宽带信道中的频率捷变频谱共享; 4）研究能够在异构网络中实现无缝多址接入的技术; 5）对信道分解、预编码/解码算法和实现架构进行原型设计和联合优化。更广泛的影响：作为一项使能技术，该项目的成功实施预计将对医疗电子、消费娱乐、应急响应和国土安全产生重大影响。除了将跨学科设计纳入课程之外，还将特别努力将研究生培训与工业实习经验相结合，并招聘和留住妇女和贫困学生。

AbstractECS-0621879L. Yang, Univ of FloridaThe objective of this proposal is to develop new decomposition techniques for multiple-input multiple-output (MIMO) channels and to design efficient MIMO transceivers. In the past, MIMO transceiver designs have always relied on the singular value decomposition (SVD) or QR decomposition to convert a MIMO channel into parallel scalar channels with vastly different gains. This either leads to the bit-loading strategy, or entails a persistent tradeoff between channel throughput and system error performance. In this proposal, the PIs aim to decompose a MIMO channel into multiple identical scalar channels so that the same modulation can be employed on all parallel channels.Intellectual Merit:To achieve this goal, the PIs propose a combined theoretical and experimental effort including the following high-level research tasks: 1) Establish the theory of flexible and robust MIMO transceiver design based on the new channel decomposition paradigm; 2) Generalize the theory to account for various levels of channel state information; 3) Optimize and adapt MIMO transceivers for frequency-agile spectrum sharing in broadband channels; 4) Investigate techniques enabling seamless multiple access in heterogeneous networks; and 5) Prototype and jointly optimize the channel decomposition, precoding/decoding algorithms and the implementation architectures.Broader Impacts:As an enabling technology, the successful implementation of this project is anticipated to significantly influence medical electronics, consumer entertainment, emergency response and homeland security. Besides integrating interdisciplinary designs into the curricula, special efforts will be devoted to combining graduate student training with industrial internship experience, and recruiting and retaining women and underprivileged students.
