Abstract In the past few years, visible light communication (VLC), which uses solid-state lightings to transmit information, has been regarded as an emerging way of wireless communication technology. For the combination of illumination and communication, dimming control is a necessary function for VLC systems. Traditional dimming control binary-based dimming schemes are spectral inefficient, while most of the multilevel transmission schemes worsen the error performance of the system. In this paper, motivated by the better characteristics of parity check codes, we propose a multilevel transmission scheme which provides better error performance maintaining spectral efficiency compared with other multilevel dimming schemes.

基于奇偶校验码的带调光控制的VLC多级传输方案

摘要 近年来，利用固态照明来传输信息的可见光通信（VLC）被视为一种新兴的无线通信技术方式。对于照明和通信的结合，调光控制是 VLC 系统的必要功能。传统的基于二进制的调光控制调光方案频谱效率低下，而大多数多级传输方案会恶化系统的误差性能。在本文中，受奇偶校验码更好特性的启发，我们提出了一种多级传输方案，与其他多级调光方案相比，该方案在保持频谱效率的同时提供了更好的错误性能。
