ITR Small Proposal 0113385/0112591Sayeed/PopovicAbstractReliable and seamless wireless connectivity in varied environments is a necessary requirement for the rich and diverse communications of the future. Space-time processing has emerged as a key enabling technology for future wireless communications: signal space dimensions are fundamental to reliable communication and antenna arrays augment the traditional dimensions of time and frequency with the spatial dimension. While recent theoretical and technological advances provide a tremendous boon for modern communications, the state-of-the-art is far from realizing the full potential of space-time processing due to significant gaps in our current understanding on two fronts:Fundamental mechanisms underlying the interaction of the space-time channel with the signal space in spatial, temporal, and spectral dimensions.Jointly optimized design of front-end hardware, antenna arrays, and signal processing algo-rithms. The overall goal of the work proposed here is an integrated approach to the design of antenna array hardware and space-time processing algorithms for significantly improved wireless link performanceat reduced cost and complexity.

在各种环境中可靠和无缝的无线连接是未来丰富多样通信的必要要求。时空处理已经成为未来无线通信的关键技术：信号空间维度是可靠通信的基础，天线阵列用空间维度增加了传统的时间和频率维度。虽然最近的理论和技术进步为现代通信提供了巨大的福音，但由于我们目前在两个方面的理解存在重大差距，最先进的技术还远远没有实现时空处理的全部潜力：时空信道与信号空间在空间、时间和频谱维度上相互作用的基本机制。共同优化设计前端硬件、天线阵列、信号处理算法。本文提出的总体目标是采用集成的方法来设计天线阵列硬件和时空处理算法，以显著提高无线链路性能，降低成本和复杂性。
