摘要
传统光通信系统没有考虑光发送、接收过程中产生的误差,具有误码率高、传输效率差,能耗高等缺陷,为此设计基于误差反馈的自适应光通信系统。该系统通过调制器模块对信号进行调制,保障输出光功率的平稳,利用光电触发板进行光通信系统的监控,然后通过误差反馈控制过程对系统发送接收过程中的误差进行控制,抑制光通信系统中存在的误差扰动,最后实验结果表明,误码率的高低受光接收功率和通信距离影响,本文系统的光通信时误码率平均值为0. 548,传输速率平均值为6. 334 byte/s,平均能耗值为0. 016 4/103J,是一种光通信效率高,误码率和能耗低的光通信系统。
Traditional optical communication systems do not take into account the errors generated in the process of optical transmission and reception,which have the defects of high bit error rate,poor transmission efficiency and high energy consumption. The system regulates the signal through the modulator module to ensure the stability of the output optical power. The optical communication system is monitored by the photoelectric trigger board. Then the error in the process of transmitting and receiving is controlled by the error feedback control process,and the error disturbance in the optical communication system is suppressed. Finally,the experimental results show that the bit error rate is affected by the optical receiving power and communication distance. The average bit error rate is 0. 548,the average transmission rate is 6. 334 byte/s,and the average energy consumption is 0. 016 4/103 J. It is an optical communication system with high efficiency,low bit error rate and low energy consumption.
