Demo: Evaluating Performance of Joint Communication and Sensing with Real-time Resource Allocation

The analysis of the trade-off between joint communication and sensing critically depends on the validity of the joint channel or environment model. In this demo, we show a set-up that can jointly characterize a monostatic sensing channel and a bistatic communication channel in the same environment. We show the CSI processing pipelines and based on that illustrate the trade-offs in resource allocation for joint communication and sensing. Concretely, we demonstrate the sensing and communication trade-off, when communication resources are allocated using communication-centric waterfilling and the remaining subcarriers can be used for monostatic sensing. This shows the fundamental trade-offs between communication and sensing in a realistic environment. The setup uses a single X410 NI USRP connected to a high-performance cloud server to handle the real-time processing.
