标题： Distortion-Aware Hybrid Beamforming for Integrated Sensing and Communication

摘要： 本文研究了一种实际的部分连接混合波束成形发射器，用于集成感知与通信（ISAC），该系统存在非线性功率放大引起的失真。 对于此ISAC系统，我们提出了一个由我们的失真感知混合波束成形设计驱动的通信速率和感知互信息最大化问题。 为解决此非凸问题，我们首先通过交替求解三个子问题，利用流形优化（MO）和我们推导出的闭式解来求解完全数字波束成形矩阵。 然后通过分解算法获得模拟和数字波束成形矩阵。 数值结果表明，与传统波束成形方法相比，所提出的算法可以提高整体ISAC性能。 显示英文摘要

摘要： This paper investigates a practical partially-connected hybrid beamforming transmitter for integrated sensing and communication (ISAC) with distortion from nonlinear power amplification. For this ISAC system, we formulate a communication rate and sensing mutual information maximization problem driven by our distortion-aware hybrid beamforming design. To address this non-convex problem, we first solve for a fully digital beamforming matrix by alternatively solving three sub-problems using manifold optimization (MO) and our derived closed-form solutions. The analog and digital beamforming matrices are then obtained through a decomposition algorithm. Numerical results demonstrate that the proposed algorithm can improve overall ISAC performance compared to traditional beamforming methods.
