Performance Analysis and Optimization of UAV‐Assisted Integrated Sensing and Communication System
To address NLOS‐induced performance degradation in urban ISAC systems, a UAV‐assisted scheme is proposed where the UAV serves as both a sensing platform and a relay. The UAV's position is optimized using a chaotic particle swarm optimization (CPSO) algorithm to maximize the weighted sum information rate, effectively balancing communication and sensing ...
