摘要

智能反射面（IRS）是一种前景广阔的信道再调整技术。在这封信中，我们研究了为可见光通信（VLC）系统部署的同步光波信息和功率传输（SLIPT）技术，并通过调整光IRS（OIRS）和收发器之间的关联来实现SLIPT，从而在保证可实现数据速率的同时最大限度地获取能量。此外，还引入了二进制分配矩阵来表示上述关联行为，然后通过放宽分配矩阵的约束条件来解决问题。此外，还提出了一种迭代优化算法和一种贪婪策略来解决非凸问题。仿真结果表明，与没有 OIRS 的方法相比，有 OIRS 辅助的方法为 VLC 系统带来了更大的收益。

Simultaneous Lightwave Information and Power Transfer for OIRS-Aided VLC System

Intelligent reflecting surface (IRS) is a promising technology for channel readjustment. In this letter, we investigate the simultaneous lightwave information and power transfer (SLIPT) technique deployed for the visible light communication (VLC) system, and implement SLIPT by adjusting the association between optical IRS (OIRS) and transceivers to maximize the harvested energy while guaranteeing the achievable data rate. Further, a binary assignment matrix is introduced to represent the association behavior mentioned above, and then the problem is solved by relaxing the constraints of the assignment matrix. Moreover, an iterative optimization algorithm and a greedy strategy are also proposed to solve the non-convex problem. The simulation results demonstrate that the OIRS-assisted approach achieves greater gain for the VLC system compared to that without OIRS.
