About this Research Topic
One of the efficient ways to tackle spectrum paucity is shared spectrum access, that will aid in paving the way for the evolution of the particularly complex ecosystem of the 5th Generation NR. Recently, more flexible spectrum usage with regards to scalable services for the IoT platform has attracted substantial attention, which motivates us to focus on communication-radar (Com-Rad) designs. Among the many research directions, this call mainly focuses on two approaches: i) Com-Rad coexistence (CRC) and ii) Dual-function Com-Rad (DFCR). Accordingly, the aim of the first category of research is to develop efficient algorithms and beamforming techniques, such that both systems can harmoniously exist without interfering with each other’s operation. Note that this is in contrary to traditional cognitive radio (CR) research as in CRC the licensed link involves a radar application with a fundamentally different function and key performance metrics, which make the joint design of the two systems challenging. On the other hand, the main aim of the DFCR design is on developing novel techniques for a single hardware platform that can simultaneously perform wireless communication and remote sensing, thus not only improving spectrum utilization efficiency, but also reducing cost of infrastructure development. This type of work will be the cornerstone for future IoT devices, including driverless vehicles, unmanned aerial vehicles (UAV) communications, and indoor positioning for personal robots, like vacuum cleaners. This research topic aims at catalyzing new technologies by bringing together contribution from researchers from academia and industry towards disruptive solutions for enabling communications in the radar spectrum and making radar applications a commodity.
