Joint Communication and Sensing Using Compressive Sensing and a Single Multi-Mode Multi-Port Antenna
Joint communication and sensing (JCAS) is of special interest due to densification in various contexts like wireless networks, airspace, and transportation networks. In this paper, a JCAS approach using a single multi-mode multi-port antenna (M3 PA) element is proposed. Towards this goal, circular beamforming is applied in order to separate communication and sensing channels, using the unique capabilities of M3
PA s. The sensing possibilities using only a single M3 PA element are evaluated assuming compressive sensing and MIMO radar signal processing including the polarization domain. Simulation results for an unmanned aerial vehicle scenario indicate a good separation of the communication link and sensing system at the cost of a slightly increased angular error.
