Communications and sensing (say, radar sensing) are developed, designed, and operated independently. However, they share many similarities such as frequency bands, hardware, and signal processing techniques. Therefore, pressed by the deficiency of available frequency spectrum, there is a demand for integrating both functionalities of communications and sensing in the same waveform and operated in the same hardware platform. This integrated sensing and communications (ISAC) has been made one of the six use scenarios of 6G cellular systems. The marriage of the two historically independent technologies brings many challenges, such as the fundamental trade-off between communications and sensing, waveform design, ADC sampling bottleneck for wideband processing, and security issues. In this talk, I will discuss the wideband signaling and interference mitigation in ISAC networks, both of which bring benefits and challenges to ISAC system design. Experiment results of ISAC will also be presented.
Husheng Li received his BS and PhD degrees, both in electrical engineering, from Tsinghua University (1998) and Princeton University (2005), respectively. He joined Qualcomm Inc. as a senior engineer after his graduation from Princeton. In 2007, he joined the EECS department of the University of Tennessee, Knoxville, where he was promoted to associate professor and full professor in 2013 and 2019, respectively. In 2022, he joined Purdue University, affiliated in both the School of Aeronautics and Astronautics and the Elmore School of Electrical and Computer Engineering. His research interest includes wireless communications, statistical signal processing, cyber physical systems, networked control, and information theory. He has received numerous best paper awards in journals such as the EURASIP Journal on Wireless Communications and Networking (2015) and conferences such as IEEE ICC (2012) and Globecom (2017).
