Abstract

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 系统的发射波束成形设计

本文提出了一种综合传感与通信（ISAC）波束成形方法，该方法可在感知多个移动目标的同时与多个用户设备（UE）进行通信。雷达估计率与通信可实现率相结合来评估 ISAC 系统的性能。半无限松弛（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。为了降低计算复杂度，提出了一种基于流形的替代算法。仿真结果验证了所提方案的有效性。
