This letter proposes an integrated sensing and communication (ISAC) beamforming method that senses multiple moving targets while simultaneously communicating with multiple user equipment (UE). The radar estimation rate is combined with the communication achievable rate to assess ISAC system performance. Semidefinite relaxation (SDR) and successive convex approximation (SCA) are used to handle the non-convex rank constraint and convexify the objective function, respectively. To reduce the computational complexity, a manifold-based algorithm is proposed as an alternative. Simulation results validate the effectiveness of the proposed schemes.

多 UE 多目标 ISAC 系统的传输波束成形设计


本信提出了一种集成传感和通信 （ISAC） 波束成形方法，该方法可感应多个移动目标，同时与多个用户设备 （UE） 通信。将雷达估计率与通信可实现率相结合，以评估 ISAC 系统性能。半定松弛 （SDR） 和连续凸近似 （SCA） 分别用于处理非凸秩约束和凸化目标函数。为了降低计算复杂性，提出了一种基于流形的算法作为替代方案。仿真结果验证了所提方案的有效性。
