Full-Duplex Wireless for (Joint-) Communication and Sensing

Abstract

In-band simultaneous full-duplex (FD) has seen rapid research in the last decade. We review the state-of-the-art in FD radios for wireless communication (including WiFi and cellular), low-power wide area networks, relays, military and other applications. We also review the use of FD in sensing, including consumer and automotive radars. We then describe how FD can usher the next generation of wireless systems employing joint communication and sensing, enabling high-directional beam steering/control and ubiquitous IoT.
