Abstract

This paper presents a novel concept for joint light source identification and localization (JLIL) with subsequent interference suppression using a liquid crystal display (LCD)-based receiver. The JLIL concept is particularly suitable for multiple-input single-output visible-light-communication settings, where an LCD-based receiver must be able to identify a desired light source before suppressing interfering ones. Given a basic visible-light-communication setup, in a first step modifications required both on the transmitter and the receiver side are identified. Subsequently, the concept for LCD-based JLIL is introduced, and its performance is illustrated by means of simulation results. In this context, intersymbol interference effects are investigated and a known ambiguity problem is overcome. Finally, results of an experimental verification are reported as a proof of concept. It is shown that the derived simulation model accurately predicts measurement results. The latter confirm a virtually error-free light source identification and precise localization within system accuracy range. Furthermore, an improved peak detection is reported. Signal-to-noise ratio measurements suggest good performance for up to

$3 \,\mathrm{m}$

using the developed hardware demonstrator.

利用带空间 LCD 滤波器的接收器，通过联合光源识别和定位实现可重构 MISO-VLC

本文提出了一种新颖的光源联合识别和定位（JLIL）概念，随后使用基于液晶显示器（LCD）的接收器抑制干扰。联合光源识别和定位概念特别适用于多输入单输出可见光通信设置，在这种设置中，基于液晶显示器的接收器必须能够在抑制干扰光源之前识别出所需光源。给出一个基本的可见光通信设置，第一步是确定发射端和接收端所需的修改。随后，介绍了基于 LCD 的 JLIL 概念，并通过模拟结果说明了其性能。在此背景下，对符号间干扰效应进行了研究，并克服了一个已知的模糊问题。最后，报告了实验验证的结果，作为概念的证明。结果表明，推导出的模拟模型能够准确预测测量结果。后者证实了在系统精度范围内几乎无误差的光源识别和精确定位。此外，还报告了改进的峰值检测。信噪比测量结果表明，使用所开发的硬件演示器，在高达 3 \,\mathrm{m}$的情况下性能良好。
