DESCRIPTION:[]Orbital angular momentum (OAM) technology has attracted much 
 research interest in recent years because of its characteristic helical ph
 ase front twisting around the propagation axis and natural orthogonality a
 mong different OAM states to encode more degrees of freedom than classical
  planar beams. Based on these properties\, OAM technique has been applied 
 to wireless communication systems to enhance spectral efficiency and radar
  systems to distinguish spatial targets without beam scanning. To simultan
 eously harness the dual benefits of OAM in both communication and radar se
 nsing\, we propose an OAM-based millimeter-wave joint radar-communications
  (JRC) system comprising a bi-static automotive radar and vehicle-to-vehic
 le (V2V) communications. Different from existing uniform circular array (U
 CA) based OAM systems where each element is an isotropic antenna\, an OAM 
 spatial modulation scheme utilizing a uniform linear array (ULA) is adopte
 d with each element being a traveling-wave antenna\, producing multiple La
 guerre-Gaussian (LG) vortex beams simultaneously. Specifically\, we first 
 build a novel bi-static automotive OAM-JRC model that embeds communication
  messages in a radar signal\, following which a target position and veloci
 ty parameters estimation algorithm is designed with only radar frames. The
 n\, an OAM-based mode-division multiplexing (MDM) strategy between radar a
 nd JRC frames is presented to ensure the JRC parameters identifiability an
 d recovery. We end the talk with a future outlook on JRC systems.\n\nSpeak
