摘　　要：针对国内外在全向紫外光通信理论模型研究方面的空白,以及系统的通信距离近、无法实现全向的问题,基于蒙特卡罗方法,建立全向紫外光通信的信道模型,分析接收信噪比;并基于紫外LED阵列及光电倍增管,通过对全向发射/接收天线的光学设计,采用4-PPM调制方式,建立速率为115.2kbit/s的全向紫外散射光通信测试系统.经过测试,接收系统的信噪比与模型仿真基本一致,实现了100m范围内的全向通信,误码率优于1×10-5.Aiming at the blank of channel model and communication system of omni-directional ultraviolet communication and the short communication distance,channel model of omnidirectional based on Monte-Carlo method was established,and the characteristics of SNR was obtained.Also based on UV led arrays and PMT,an omni-directional UV communication system with a communication rate of 115.2kbit/s was developed,though the omni-directional optical design of transmitting/receiving antenna and 4-ppm modulation.The experimental results of SNR were consistent with the simulation results.The omni-directional UV communication was established in the 100 mrange,and the bit error rate（BER）was better than 1×10-5.
