Abstract
A Joint Radar and Communication (JRC) system utilizing 5G signals is proposed. To address the challenges of detecting multiple closely spaced targets in the range-Doppler map, an iterative strong target cancellation algorithm is introduced. This algorithm mitigates the impact of dominant targets, which can obscure weaker signals and complicate detection for conventional methods such as range- or speed-based searches and CFAR algorithms. By progressively canceling strong targets, the method enhances the detection and differentiation of weaker ones, significantly improving overall system performance. Its adaptability and robustness make it suitable for JRC systems, ensuring accurate detection in resource-constrained and spectrum-sharing environments. A JRC prototype based on software-defined radio (SDR) is developed. Extensive simulations and experiments with the prototype validate the algorithm’s effectiveness.
期刊介绍:
The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
