Demonstration of Joint Communication and Sensing with Fully Digital Arrays

This hardware demonstration showcases a fully digital mono-static joint communication and sensing approach for multi-antenna arrays. Using a a software defined radio testbed consisting of two units transmitting and receiving standard communication waveforms in an in-band full duplex fashion over multiple antennas, it is shown that a range-angle radar image can be estimated from environmental scattering without impacting the communication performance. Such an approach can be key enabler for joint communication and sensing deployment using communication network infrastructure.
