摘要

在很大程度上

室内可见光通信系统的表现受到可见光多径传播信道的影响.已有研究尚局限于表征朗伯型光源波束配置下可见光无线信道特性

客观上忽视了对光源波束维度潜在差异化影响的关注与讨论.不同于已有研究

本文重点聚焦于非朗伯型波束条件下可见光无线信道的多径传播效应.为便于同传统朗伯型信道进行比较分析

本文主要从信道脉冲响应、信道频率响应以及信干噪比等方面进行量化表征.为不失一般性

在经典中型尺寸室内应用场景中

本文引入了两种典型的非朗伯波束进行量化建模分析.较之于朗伯波束

量化结果显示在信干噪比方面

两种非朗伯波束可分别引入约1 dB的增益及4 d B的损伤.因此

非朗伯波束客观上为可见光通信领域提供一个崭新的设计维度.

Abstract

To a large extent

the performance of indoor visible light communication systems is affected by the visible light multipath propagation channel. Previous works are still limited to characterizing the characteristics of the visible light wireless channel characteristics under Lambertian source beams configuration. Objectively

the potential differential effects of beam dimensions of light sources are waiting for concerns and discussions. Unlike previous studies

this paper focuses on the frequency selectivity effect of visible light wireless channels under non-Lambertian beam conditions. For comparing with the conventional Lambertian channel

this work mainly quantifies the channel impulse response

channel frequency response and signal-to-interference & noise ratio. Without loss of generality

in classical indoor application scenario with medium-size

this work discusses the numerical modeling and analysis of two typical non-Lambertian beams. Compared with the Lambert beam

the numerical results illustrate that in SINR aspects

the two non-Lambertian beams could introduce about 1 dB gain and 4 dB damage

respectively. Therefore

objectively

the non-Lambertian beams provide one novel design dimension for visible light communications domain.
