EARS: Interference-Aware RF Theory and Design

目标：该多学科计划的目标是开发颠覆性射频(RF)技术，通过利用物理层干扰管理和集成接收器设计方面的最新进展，在物理层提供显著的频谱效率提升。智力优势：该项目的智力优势包括以下三个方面：(I)用于增强动态范围的射频前端信号投影和消除；(Ii)用于以接收器为中心的干扰管理的受控反射器；以及(Iii)以接收器为中心的干扰管理的基本原理。第一个推力利用关于干扰结构的信息来在接收器链的早期抑制干扰，从而保护后续级不受系统的全动态范围要求的影响。第二个推力开发了射频接收器，它兼有受控、协调反射器的作用，并能够改变附近接收器的有效通道增益。第三个推力根据上述收发信机的新能力制定了新的干扰管理战略，并研究了这些技术下频谱效率的基本限制。更广泛的影响：通过发展“信息理论”和“射频集成电路”两个领域之间的合作和交流，该项目在这两个领域开辟了新的视野。该项目不仅通过提高网络容量影响国家经济，还通过刺激技术进步来影响国家经济，这些技术进步可以很容易地转移到无线和电子行业，推动这些领域的经济增长。该项目还为本科生提供了研究经验的机会，并包括几项外展活动。

Objective: The objective of this multidisciplinary program is to develop disruptive Radio Frequency (RF) technologies that provide significant spectral efficiency gains at the physical layer, by leveraging recent advances in physical layer interference management and integrated receiver design. Intellectual merit: The intellectual merits of this project is composed of the following three thrusts: (i) RF Front-End Signal Projection and Cancellation for Enhanced Dynamic Range, (ii) Controlled Reflectors for Receiver-Centric Interference Management, and (iii) Fundamentals of Receiver-Centric Interference Management. The first thrust utilizes information about the structure of the interference to suppress it early in the receiver chain, shielding subsequent stages from full dynamic range requirements of the system. The second thrust develops RF receivers which double as controlled, coordinated reflectors, and are able to alter the effective channel gains to nearby receivers. The third thrust develops new interference management strategies in the light of the aforementioned new capabilities of transceivers and studies the fundamental limits of spectral efficiency under such technologies. Broader impacts: By developing collaboration and communication between two fields of "information theory" and "RF Integrated Circuits", this program opens new horizons in both fields. This project impacts the nation's economy not only by enabling greater network capacity, but also by spurring technological advances that can easily be transferred to the wireless and electronics industries, driving economic growth in those areas. This project also provides opportunities for research experience for undergraduates and includes several outreach activities.
