Title: Optimal Waveform Design for Dual-functional Radar-Communications: From Theory to Experiments
Date: 7 June 2022
Time: 9:00 AM Eastern (New York time)
Duration: Approximately 1 Hour
Presenters: Dr. Athina Petropulu, Dr. Christos Masouros, Dr. Fan Liu
Based on the IEEE Xplore® article: Toward Dual-functional Radar-Communication Systems: Optimal Waveform Design
Published: IEEE Transactions on Information Forensics and Security, IEEE Transactions on Signal Processing, June 2018 available in IEEE Xplore®
As the standardization of 5G gradually solidifies, researchers are speculating what 6G will be. One common theme is that radio sensing functionality would be integrated into 6G networks in a low-cost and fast manner. Therefore, the future cellular network could image and measure the surrounding environment to enable advanced location-aware services, ranging from the physical layer to application layers. This type of research is typically referred to as Integrated Sensing and Communication (ISAC).
In this webinar, we will introduce our recent results on optimal dual-functional radar-communications (DFRC) waveform design, which is regarded as a key enabler for the practical implementation of ISAC. DFRC waveforms are specifically tailored signals that are able to accomplish sensing and communication signaling tasks simultaneously. We will commence by introducing the background and applications of ISAC. Then we focus on a general DFRC transmission scenario, where a single MIMO base station (BS) communicates with downlink cellular users and detects radar targets simultaneously. Several design criteria will be discussed for minimizing the downlink multi-user interference (MUI) under radar-specific constraints, namely, omni- and directional beampattern constraints, similarity constraint, and constant-modulus constraint. Finally, we will verify the proposed waveform design approaches through both simulation and experimental results based on the software-defined radio (SDR) platform.
