In contrast\, over the past three decades\, growing attention ha s been directed toward orbital angular momentum (OAM)\, which arises from helical (twisted) phase fronts and provides an additional degree of freedo m through its orthogonal modal structure. In this talk\, we explore the us e of OAM for integrated sensing and communications (ISAC)\, with the goal of enhancing spectral efficiency and spatial resolution in automotive scen arios. Unlike conventional uniform circular array (UCA)-based implementati ons\, our approach employs a uniform linear array (ULA) with traveling-wav e antennas to synthesize multiple Laguerre-Gaussian vortex beams. The prop osed system embeds communication data within radar waveforms while enablin g joint estimation of target position and velocity using radar-only frames . An OAM-based mode-division multiplexing strategy is used to separate sen sing and communication functionalities\, ensuring reliable parameter recov ery. We conclude with perspectives on the future of ISAC systems.\n[Joint work with Wanghan Lv]\n\nSpeaker: Dr. Kumar Vijay Mishra\n\n[]\n\nKumar Vi jay Mishra (S’08-M’15-SM’18) obtained a Ph.D. in electrical engineer ing and M.S. in mathematics from The University of Iowa in 2015\, and M.S. in electrical engineering from Colorado State University in 2012\, while working on NASA’s Global Precipitation Mission Ground Validation (GPM-GV ) weather radars.
