ITR: High Performance "Signal Processing" Antenna Array Systems for Wireless Communications

提出了一种新的多天线无线系统设计方法。其基本思想是融合了天线设计、射频电路和器件技术、实时数字信号处理技术和通信理论中的技术和概念。为体现这一思想，提出了新的高性能“信号处理”阵列前端的设计方案及其相关的通信处理研究。建议的阵列前端涵盖从天线阵列、射频电路到中频或基带输出的广泛硬件。作为一个测试平台，我们提出了一种单通道射频接收天线阵列和局部单元空间复用(SMILE)。通信处理方面的研究主要集中在空时传播信道的研究和连续相位调制(CPM)编码在基于该前端的多输入多输出(MIMO)系统中的应用。对硬件体系结构和通信算法融合中的系统级问题进行了研究。该项目的跨学科性质确保了来自不同学科的教职员工和学生之间的密切互动。因此，该项目将使微波和射频技术、实时信号处理和无线通信等多个领域的课程和研究生研究课题受益。

A new design methodology for multi-antenna wireless system is proposed. The essential idea is based on the fusion of technologies and concepts in the antenna design, RF circuit and device technology, real-time DSP technology and communication theory. To embody this idea, novel designs of high-performance "signal processing" array front-ends and the associated communication processing research are proposed. The proposed array front-ends cover a broad range of hardware from the antenna array, RF circuits all the way to IF or baseband outputs. As a testbed, we propose a receiving antenna array with a single RF-channel and Spatial MultIplexing of Local Elements (SMILE). The communication processing research is focused on the study of space-time propagation channels and the applications of Continuous Phase Modulation (CPM) coding scheme in a Multiple Input Multiple Output (MIMO) system based on the proposed front-end. Studies of system level issues in merging the hardware architectures and communication algorithms are also proposed. The interdisciplinary nature of this project ensures close interactions among faculty members and students from different disciplines. Hence, the project will benefit the curriculums and graduate research subjects in multiple areas such as microwave and RF technology, real-time signal processing and wireless communication.
