摘要

提出了一种利用图像传感器作为接收机获取实时位置相关信息的自由空间可见光通信系统。由于大气湍流影响通信质量，分析大气湍流对设计实用的通信系统具有重要意义。本文对大气湍流通道进行了分析。提出了表征和量化大气效应对图像传感器通信影响的方法。给出了CMOS图像传感器作为接收机的系统噪声模型。在此基础上，研究了考虑大气湍流的OOK调制系统的误码概率。

Performance analysis of image sensor communication over free space optical channel

This paper presents a free space visible light communication (VLC) system using an image sensor as a receiver to acquire position related timely information. Since the atmospheric turbulence affects the communication quality, the analysis of atmospheric turbulence is very important for designing a practical communication system. In this paper, the atmospheric turbulence channel is analyzed. The method of characterizing and quantifying the influence of atmospheric effect to image sensor communication is presented. The noise model of the system using CMOS image sensor as a receiver is given. Furthermore, the bit error probability of the system using OOK modulation considering atmospheric turbulence is studied.
