摘要

数据密集型服务和应用的发展不断推动无线通信系统对更高的数据传输速率的需求,从而耗尽了射频(RF)频谱。由于可见光(VL)频谱具有未授权的巨大带宽,可见光通信(VLC)的出现被认为是缓解与射频频谱稀缺相关的制约因素的潜在解决方案。然而,视距要求和可见光无法穿透不透明障碍物仍然是实现更广覆盖范围的严峻挑战。在 VLC 系统中加入合作通信是应对这一挑战的主要解决方案之一。虽然目前在这一领域正在进行各种研究,但公开文献中还没有关于各种进展、解决方法和设计挑战的整体报告。因此,在本文中,我们的主要目标是回顾合作 VLC 系统的最新研究成果。首先,我们从理论和分析的角度讨论了合作 VLC 系统各组成部分之间的关系。其次,我们将这方面的各种贡献归类为媒体访问控制 (MAC)、混合 VLC-RF、电力线通信-VLC (PLC-VLC) 和带能量收集的 VLC。在既定分类的基础上,我们确定了各种系统设计和评估方法、优化问题、解决问题的方法及其局限性。第三,我们确定了从提交的论文中获得的各种启示,这些启示可作为实际系统设计的指南。最后,我们确定了各种设计挑战和未来研究的开放领域。

Cooperative visible light communications: An overview and outlook

The evolution of data-intensive services and applications continues to drive the need for higher data rates in wireless communication systems, consequently depleting the radio frequency (RF) spectrum. Due to the unlicensed and enormous bandwidth available in the visible light (VL) spectrum, the emergence of visible light communication (VLC) has been considered a potential solution to alleviate the constraints associated with RF spectrum scarcity. However, the line-of-sight requirement and the inability of VL to penetrate opaque obstacles remain a daunting challenge in realizing a wider coverage area. The incorporation of cooperative communication in VLC systems serves as one of the primary solutions to address this challenge. Though various investigations are currently being conducted in this domain, a holistic report of various advances, solution approaches, and design challenges has not been captured in the open literature. Therefore, in this paper, our main goal is to present a review of the state-of-the-art research on cooperative VLC systems. Firstly, we provide a background discussion to establish the relationship between various components of cooperative VLC systems from a theoretical and analytical perspective. Secondly, we categorize various contributions in this direction under media access control (MAC), hybrid VLC-RF, power line communication-VLC (PLC-VLC), and VLC with energy harvesting. Based on the established categories, we identify various system design and evaluation methods, optimization problems, solution approaches adopted to tackle the problems, and their limitations. Thirdly, we identify various insights obtained from the presented papers that could serve as guidelines for practical system design. Finally, various design challenges and open areas for future research are identified.
