Link Communication Error Rate Control Method for Interference Optical Communication System

由于目前振动干扰的光通信系统链路通信,易出现二次误码,通信信道被占用,导致链路通信误码率控制效果较差。提出了干扰光通信系统的链路通信误码率控制方法。分析光通信系统链路通信信道特性,获得干扰光通信系统的链路通信信道的噪声密度函数,通过计算振动干扰下的链路通信误码率,结合深度学习算法构建溯源抑振模型,从而计算出收取信号、等效噪声及噪声分布指数,得到优化后的遍历容量与功率分配方法,完成干扰光通信系统的链路通信误码率控制。分析控制后通信的误码率、信道容量与平均接入时间。实验结果表明,所提方法能够降低通信信道的占用率,且不会出现二次误码,控制效果较好,振动干扰下的平均误码率仅为5%。

Due to the link communication of the current optical communication system with vibration interference,secondary errors are prone to occur,and the communication channel is occupied,resulting in poor control of the link communication error rate.A method for controlling the bit error rate of the link communication that interferes with the optical communication system is proposed.Analyse the characteristics of the link communication channel of the optical communication system,obtain the noise density function of the link communication channel that interferes with the optical communication system,calculate the bit error rate of the link communication under vibration interference,and build a traceability vibration suppression model in combination with deep learning algorithms to calculate.The received signal,equivalent noise and noise distribution index are obtained to obtain the optimised traversal capacity and power allocation method.The link error rate control of the interference optical communication system is completed.Analyse the bit error rate,channel capacity and average access time of the communication after control.The experimental results show that the proposed method can reduce the communication channel’s occupancy rate without secondary errors.The control effect is good,and the average error rate under vibration interference is only 5%.
