A Tutorial on Joint Radar and Communication Transmission for Vehicular Networks—Part III: Predictive Beamforming Without State Models

In Part I and II of this three-part tutorial on dual-functional radar-communication (DFRC) design for vehicular networks, we overviewed the basics radar communication systems state art in DFRC respectively. As III tutorial, address issue predictive beamforming vehicle-to-infrastructure (V2I) links without need explicit evolution models. The beam tracking is done with aid signals transmitted by road side unit (RSU). vehicle's location parameters are estimated exploiting reflected echoes signals. Given these estimates, propose a prediction method to predict next position vehicle, specifying model. Finally, verify superiority proposed approaches via numerical simulations, which show that technique outperforms conventional benchmark schemes terms achievable rate.
