SPS ISAC-TWG Webinar: Trade-offs and Non-idealities in ISAC Systems: From Monostatic to Bistatic
Date: 28-August-2025
Time: 08:00 AM ET (New York Time)
Presenter: Dr. Musa Furkan Keskin
About this topic:
Integrated sensing and communication (ISAC) emerges as a cornerstone technology for 6G, embedding sensing capabilities directly into wireless networks. Operating at high carrier frequencies, a common technological trend in the evolution towards 6G, may amplify the impact of hardware impairments (HWIs) on both functionalities in ISAC systems, more significantly affecting the sensing capability. This talk begins with an overview of OFDM-based ISAC systems and highlights two fundamental trade-offs, namely, the time-frequency trade-off and the spatial trade-off, resulting from the choice of modulation order and the ISAC beamforming strategies, respectively. The presenter will then discuss key differences between sensing and communication under HWIs in monostatic and bistatic configurations, focusing on inter-carrier interference (ICI) and phase noise (PN). Departing from the traditional approach of treating such effects solely as impairments, he will show how these non-idealities can be exploited to improve sensing performance (even beyond that obtained via ideal, impairment-free ISAC systems), as opposed to their purely detrimental nature in communications. Finally, he explores how data-aided sensing in bistatic ISAC can bridge the performance gap to an equivalent monostatic system with perfect knowledge of data.
