摘要

自由空间光通信是解决新兴的自由空间光通信接入网的一种最有前途的方法。地面FSOC系统的优点是:无相互干扰,数据速率高,无线连接无无线电规则,安装快捷方便,传输数据不易被窃听,成本相对较低。然而,由于恶劣的天气条件,为了建立可靠的高速数据通信,需要减轻激光功率衰减。本文描述了现场可编程门阵列(FPGA)中自适应模糊逻辑控制器(AFLC)作为闭环控制配置(CLCC)的设计和实现,以减轻大气的不利影响。为了提高FSOC的性能,本文还提出了用于对准、跟踪和定位(ATP)激光束的光电结构。对实验结果进行了分析。

Digital Design of Fuzzy Logic Controller for Optical Beam Steering in Free Space Optical Communication
Free Space Optical Communication is one of the most promising approach to address the emerging free space optical communication access network. The terrestrial FSOC systems advantageous are: no mutual interference, capability of high data rates, radio regulation free wireless connectivity, fast and easy installation, difficult eavesdropping on transmitted data and relatively low cost. However, due to adverse weather conditions the laser power attenuation is to be mitigated in order to establish the reliable high speed data communication. In this paper, design and implementation of an Adaptive Fuzzy Logic Controller (AFLC) in Field Programmable Gate Array (FPGA) as a Closed Loop Control Configuration (CLCC) for mitigating the atmospheric adverse effects is described. The developed Opto-electronic architecture for Aligning, Tracking and Positioning (ATP) the laser beam in order to enhance the performance of the FSOC is also presented. The experimental results are analyzed.
