摘要

数据传输是未来物联网(IoT)的关键因素之一。可重构智能表面(RIS)和反向散射通信(BackCom)技术需要一种实现低功耗可持续传输的解决方案,这在无线通信领域显示出巨大的潜力。因此,本文介绍了一种基于 RIS 的 BackCom 系统,其中 RIS 接收来自基站(BS)的能量,并通过反向散射来自基站的信号来发送信息。为了最大限度地提高所有物联网设备(IoTDs)的总和速率,我们利用另一种优化算法联合优化了时间分配、RIS 反射相移和基站的发射功率。仿真结果表明了所提出的无线通信方案和算法在物联网网络中的有效性和可行性。

Reconfigurable Intelligent Surface-Based Backscatter Communication for Data transmission
Data transmission is one of the critical factors in the future of the Internet of Things (IoT). The techniques of a reconfigurable intelligent surface (RIS) and backscatter communication (BackCom) are in need of a solution of realizing low-power sustainable transmission, which shows great potential in wireless communication. Hence, this paper introduces an RIS-based BackCom system, where the RIS receives energy from a base station (BS) and sends information by backscattering the signals from the BS. To maximize the sum rate of all IoT devices (IoTDs), we jointly optimized the time allocation, the RIS-reflecting phase shifts and the transmit power of the BS by exploiting an alternative optimization algorithm. The simulation results illustrate the effectiveness and the feasibility of the proposed wireless communication scheme and the proposed algorithm in IoT networks.
