Efficient MIMO Transceivers Based on Channel Decomposition Techniques

abstractecs - 0621879 l。本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。在过去，MIMO收发器设计一直依赖于奇异值分解（SVD）或QR分解来将MIMO信道转换为具有巨大增益的并行标量信道。这要么导致位加载策略，要么需要在通道吞吐量和系统错误性能之间进行持久的权衡。在这个提议中，pi的目标是将一个MIMO信道分解成多个相同的标量信道，以便在所有并行信道上使用相同的调制。智力优势：为了实现这一目标，pi提出了理论和实验相结合的努力，包括以下高水平的研究任务：1)建立基于新信道分解范式的灵活鲁棒MIMO收发器设计理论；2)对理论进行概括，以解释不同层次的通道状态信息；3)优化和调整MIMO收发器，实现宽带信道的频率捷变频谱共享；4)研究在异构网络中实现无缝多址接入的技术；5)原型化并共同优化信道分解、预编/解码算法和实现架构。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、消费者娱乐、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外，还将特别努力将研究生培训与工业实习经验结合起来，并招募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.
