• Title: "Dual-Function Radar Communication System with Communication and Radar Performance Tradeoff"
• Abstract: We will present a dual-function radar communication (DFRC) system that uses the available bandwidth efficiently for both sensing and communication. The system transmits wideband, orthogonal frequency division multiplexing (OFDM) waveforms and allows the transmit antennas to use subcarriers in a shared fashion. A novel, low complexity target estimation approach is proposed to overcome the coupling of radar target parameters and transmitted symbols that arises in that case. When all subcarriers are used in a shared fashion, the proposed system achieves high communication rate but its sensing performance is limited by the size of the receive array. We show that when some of the subcarriers are reserved for exclusive use by one transmit antenna each (private subcarriers), the communication rate can be traded off for improved sensing performance. The latter can be achieved by using the private subcarriers to construct a larger aperture virtual array that yields higher resolution angle estimates. The system is endowed with beamforming capability, via waveform precoding, where the precoding matrix is optimally designed to meet a joint sensing-communication system performance metric.

KEYNOTE 2:

• Speaker: Prof. Christos Masouros (University College London)
• Title: "The Multi-functional Wireless Network of 6G and Beyond: New Signalling, Synergies and Trade-offs"
• Abstract: The integration of sensing and communication functionalities is seen as a key enabling technology for 6G networks to provide services beyond communications. It has obvious gains in energy-, hardware- and cost- efficiency through the use of dual-functional hardware, but their co-design also offers opportunities in flexible trade-offs and new synergies between sensing and communication. In this talk, I discuss signalling strategies that enable information exchange together with target detection from a single transmission. These range from radar-centric and communication-centric, to joint signalling. I present some results and proof of concept experiments from my team’s work in the area, that underline the benefits of the co-design in offering a graceful trade-off between the two functionalities. I then discuss use cases that highlight potential synergies between sensing and communications. I conclude with some thoughts on research opportunities and the road ahead.
