摘要

本文提出了一种应用于可见光蜂窝网的自由曲面光学发射天线，用于改善整个网络范围内的信号质量以提高系统的通信性能.首先基于能量映射关系和斯涅尔定律，设计了目标光分布区域为矩形的基于自由曲面透镜的光学发射天线，应用该天线能使半导体发光二极管（LED）光源发出的光信号均匀分布在0.8 m × 0.8 m的正方形范围内.而后将设计的光学发射天线应用于可见光蜂窝网，并进一步对网络接收区域的光信号质量和系统性能做了分析.结果表明，在一个3 m × 3 m × 3 m房间中安装有16个LED光源作为接入点，采用所设计的自由曲面光学发射天线，网络覆盖区域的光信号分布均匀度达到了0.8以上，同信道干扰基本消除，平均信干噪比为12.6 dB，系统具有较好的误码率性能，能够有效地保证可见光蜂窝网的通信质量.

Abstract

A novel optical transmitting antenna based on free-form lens is proposed for visible light cellular network in order to improve the signal quality in the whole coverage area and communication performance of the system. Based on the energy mapping relation and Snell’s law

the optical transmitting antenna based on free-form lens is designed to realize rectangle light receiving areas. Using this optical transmitting antenna

the light signal from light emitting diodes (LED) source can be distributed uniformly in a square area of 0.8 m × 0.8 m. On this basis

a visible light cellular network with the novel optical transmitting antenna is applied

of which the quality of the receiving light signal and system performance are further investigated. It is demonstrated that in a 3 m × 3 m × 3 m room with 16 LEDs using the designed optical antenna

the uniformity of light distribution in the light network converage reaches 0.8. With the elimination of co-channel interference

the average signal to interference and noise ratio (SINR) is 12.6 dB

which can effectively improve the bit error ratio (BER) and ensure the communication performance of visible light cellular networks.
