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.

目标：这个多学科项目的目标是通过利用物理层干扰管理和集成接收器设计的最新进展，开发颠覆性射频（RF）技术，在物理层提供显著的频谱效率增益。智力优势：本项目的智力优势由以下三个重点组成：(i)增强动态范围的射频前端信号投影和抵消，（ii）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础。第一个推力利用有关干扰结构的信息在接收器链的早期抑制它，屏蔽后续阶段对系统的全动态范围要求。第二个重点是开发射频接收器，它可以作为可控的协调反射器，并且能够改变附近接收器的有效信道增益。第三个重点是根据上述收发器的新功能开发新的干扰管理策略，并研究这些技术下频谱效率的基本限制。更广泛的影响：通过发展“信息论”和“射频集成电路”两个领域之间的合作和交流，该项目在两个领域都开辟了新的视野。该项目对国家经济的影响不仅在于增加网络容量，还在于刺激技术进步，这些技术进步可以很容易地转移到无线和电子行业，从而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，并包括一些外展活动。
