In this letter, a reconfigurable intelligent surface (RIS)-assisted dual-hop visible light communication (VLC)/radio frequency (RF) system in indoor scenarios is proposed, in which the first link is a VLC link while an RIS is deployed in the second RF link. More specifically, a relay first converts the received optical signal into the RF signal blue using either decode-and-forward or amplify-and-forward protocols and then forwards it to the RIS. The RIS alters the electromagnetic response of the impinging waves to provide connectivity between the RF destination and optical source. Based on this model, closed-form expressions for the outage probability and bit error rate (BER) are derived. Also, an asymptotic analysis for the outage probability is presented. Finally, simulation results are provided to verify our analytical results.

通过可重构智能表面的室内混合双跳 VLC/RF 系统

在这封信中，提出了一种室内场景的可重构智能表面（RIS）辅助双跳可见光通信（VLC）/射频（RF）系统，其中第一条链路是VLC链路，而RIS部署在室内场景中。第二个射频链路。更具体地说，中继首先使用解码转发或放大转发协议将接收到的光信号转换为 RF 信号蓝色，然后将其转发到 RIS。RIS 改变撞击波的电磁响应，以提供射频目的地和光源之间的连接。基于该模型，推导出中断概率和误码率 (BER) 的封闭式表达式。此外，还提出了中断概率的渐近分析。最后，提供了仿真结果来验证我们的分析结果。
