Dual-Function Radar-Communication System Aided by Intelligent Reflecting Surfaces [PDF]
International Conference on Security and Management, 2022 We propose a novel design of a dual-function radar-communication (DFRC) system aided by an Intelligent Reflecting Surface (IRS). We consider a scenario with one target and multiple communication receivers, where there is no line-of-sight between the ...
