摘要

建立了一种基于MIMO的室内二次反射可见光通信的信道模型。通过模型仿真

从不同位置处接收面上探测器的不同间距、不同面积以及接收面横向、纵向旋转方面

分析了室内MIMO可见光通信的接收特性。仿真结果表明

在满足信号可恢复的条件下

接收面探测器间距

的变化对光信号接收的影响很小

不同接收位置的接收信噪比(SNR)也呈现不同的分布。另外

接收面横向旋转不会影响光信号接收

而纵向旋转具有一定的限制范围。

Abstract

An indoor MIMO visible light communication system based on secondary reflection was proposed in this paper. Through model simulation

with the change of different spacing and different size of detectors on receiving surface at different position and different horizontal or vertical rotation of receiver

the receiving characteristics of indoor MIMO visible light communication were analyzed. The simulation results demonstrate that the changes of the detector spacing on receiving surface have little effect to the receiving optical signal

under the condition of signal can be recovered. SNR has different distribution when receiver is placed at different position. Moreover

the horizontal rotation of receiver has no effect on receiving optical signal

but the vertical rotation has a certain rotation range.
