摘要
由于光纤通讯信号是动态的,容易出现变异情况,无法获取干扰位置精准信息,导致干扰抑制效果不佳,所以提出了基于定位算法的光纤通讯信道干扰抑制方法。构建定位适应度函数,计算干扰源位置坐标,确定信道干扰位置。设计基站路由节点均衡分配流程,实现光纤通讯基站安全承载。计算信道分配后链路稳定性概率,避免因通信环境动态性而导致路由失效。构建簇间多跳路由通信机制,获取通讯信道特征配准结果,实现动态反馈干扰抑制。构建以时延准确度为目标的误差模型,优化干扰抑制结果,避免通信过程受到非视距场景的干扰影响。由实验结果可知,该方法获取的干扰坐标与实际干扰坐标存在最大为0.2 m的误差,只需100次迭代就能达到稳定状态,抑制干扰能力强。
Because the fiber optic communication signal is dynamic and prone to variation, the accurate information of jamming position cannot be obtained, which leads to poor jamming suppression effect. Therefore, a jamming suppression method based on positioning algorithm is proposed for fiber optic communication channel. The location fitness function is constructed, the coordinates of the interference source are calculated, and the channel interference location is determined. The balanced allocation process of base station routing nodes is designed to realize the safe bearing of optical fiber communication base station. The probability of link stability after channel allocation is calculated to avoid route failure due to dynamic communication environment. The multi-hop routing communication mechanism between clusters is constructed to obtain the feature registration results of communication channels and achieve dynamic feedback interference suppression. An error model with delay accuracy as the objective was constructed to optimize the interference suppression result and avoid the interference influence of non-line-of-sight scenes in the communication process. The experimental results show that the interference coordinate obtained by this method has a maximum error of 0.2m with the actual interference coordinate, and it only takes 100 iterations to reach a stable state, with strong interference suppression ability.
