A Tutorial on Joint Radar and Communication Transmission for Vehicular Networks—Part II: State of...

In Part I of this three-part tutorial on dual-functional radar-communication (DFRC), we overviewed the fundamental elements of DFRC. As Part II of the tutorial, this letter overviews the state-of-The-Art (SoA) in DFRC, with a particular emphasis on the use of the technique for seamless connectivity in the vehicular network. We commence by introducing the conventional beam tracking approaches for millimeter wave (mmWave) communication systems, based exclusively on communication signalling and feedback, followed by the DFRC based schemes tailored for the vehicular network. Finally, we evaluate a number of SoA DFRC schemes through comparative simulations.
