Automotive short-range radar systems use the radio spectrum to detect obstacles such as other vehicles or pedestrians. Radar can alert the driver for possible impact, automatically trigger safety devices and ultimately undertake maneuvers to avoid or mitigate collisions. Thus, according to 5G vision document, in the context of road transport, we will see fully automated vehicles equipped with short-range radar in near future. The mm-wave band (beyond 30GHz frequency) for radar is very promising approach for automotive industry mainly since larger bandwidth of higher frequencies provides finer resolution of the estimated target, and hence better performance at short-ranges. It is recognized that the mm-wave solution is a long-lasting solution for all vehicle manufacturers to improve active safety devices, thus European Commission defined the frequency range 77 GHz to 81 GHz (79 GHz) for short-range automotive radar system. On the other hand, due to the idea of Internet of Things (IoT), high demands for high data rates are predicted which make it impossible to work in current dedicated frequency bands for V2V and V2X communications.
These facts motivate us to design a unified architecture for a joint radar-communication scenario applied in a network of future smart connected cars to support both short-range radar and data communications. The key motivation behind this unified system design is to address the problem of spectrum shortage through coexistence where both systems can share the same frequency band and use it more efficiently than two traditional separate systems.


Sayed Hossein Dokhanchi received the B.S. degree from the Sharif University of Technology in 2007, and the M.S. degree from the IUST in 2010, all in electrical engineering. He was with Telecommunications Infrastructure Company from 2010 to 2016. He is currently pursuing the Ph.D. with SnT, University of Luxembourg, under supervision of professor Ottersten. His research interest is applied physics and mathematics, currently working on vehicular radar and communication systems.
