In sixth generation (6G) mobile communications, Dual Function Radar and Communication (DFRC) signals are employed in Internet of Vehicles (IoV) to ensure traffic safety by simultaneously sensing and communication.

摘要

In sixth generation (6G) mobile communications, Dual Function Radar and Communication (DFRC) signals are employed in Internet of Vehicles (IoV) to ensure traffic safety by simultaneously sensing and communication. This paper considers a high-accuracy target detection scheme for pedestrian with potential safety risks while minimizing the total power consumption. Therefore, an optimization problem is formulated to maximize the accuracy-to-power ratio (APR) under the communication quality of service (QoS) constraint. After detection accuracy analysis and problem transformation, a feasible solution is derived based on convex optimization theory. The detection performance of the proposed scheme under various conditions is evaluated, and the results demonstrate that the proposed scheme can achieve a tradeoff between detection accuracy and total power consumption.
