摘要

这封信研究了同时光波信息和功率传输（SLIPT）的混合正交频分多址和非正交多址（OFDMA-NOMA）技术，用于在高频衰落信道中运行的可见光通信（VLC）系统。通过共同调整对间功率分配系数、直流偏置和功率分裂系数，建立了考虑信息接收和能量收集性能的优化问题。采用了一种基于改进的算术优化算法（m-AOA）的资源分配方案。结果表明，所提出的资源分配方案使基于slip的混合多址VLC系统的能源效率提高了15%，同时与传统的固定功率分配方案相比，用户公平性也得到了提高。

Resource Allocation for SLIPT-Enabled Hybrid OFDMA-NOMA VLC System

This letter investigates a simultaneous lightwave information and power transfer (SLIPT)-enabled hybrid orthogonal frequency division multiple access and non-orthogonal multiple access (OFDMA-NOMA) technology for visible light communication (VLC) systems operating in a high-frequency fading channel. An optimization problem considering information receiving and energy harvesting performance is formulated by jointly adjusting the inter-pair power allocation factor, direct current bias, and power splitting coefficient. A resource allocation scheme based on a modified arithmetic optimization algorithm (m-AOA) is adopted. The results demonstrate that the proposed resource allocation scheme improves energy efficiency (EE) of the SLIPT-enabled hybrid multiple access VLC system by 15%, while the user fairness is also enhanced compared to the conventional fixed power allocation scheme.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
