Abstract

In this letter, an integrated sensing and communication (ISAC) system is investigated. Initially, we introduce a design criterion wherein sensing data acquired from the preceding time slot is employed for instantaneous optimal beamforming in the succeeding time slot, aiming to enhance the communication rate. Subsequently, the development of optimal beamforming is addressed, and a high-caliber suboptimal resolution is derived utilizing successive convex approximation (SCA) techniques combined with the iterative rank minimization (IRM) methodology. Our evaluations, grounded on numerical analyses, reveal that the communication rate of the introduced beamforming strategy surpasses that of conventional omnidirectional sensing and pilot based approaches.

综合传感与通信系统中的时序辅助动态示波器优化

在这封信中，我们研究了一种集成传感与通信（ISAC）系统。首先，我们介绍了一种设计准则，即利用前一时隙获得的传感数据在后一时隙进行瞬时优化波束成形，以提高通信速率。随后，我们讨论了最佳波束成形的发展，并利用连续凸近似（SCA）技术结合迭代秩最小化（IRM）方法，得出了高精度的次优分辨率。我们基于数值分析进行的评估显示，引入的波束成形策略的通信速率超过了传统的全向传感和基于先导的方法。
