A Tutorial on Joint Radar and Communication Transmission for Vehicular Networks-Part II: State of the Art and Challenges Ahead

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.

Automated summary

This tutorial is divided into three parts, with Part I covering the fundamental elements of DFRC and Part II focusing on the latest state-of-the-art developments in DFRC for seamless connectivity in vehicular networks. The letter introduces conventional beam tracking approaches for millimeter wave communication systems and DFRC schemes tailored for the vehicular network, followed by an evaluation of several SoA DFRC schemes through comparative simulations.
