摘要 本文提出了一种新的基于极大似然法的椒盐噪声滤波算法。在传统BP 算法中引入 了极大似然估计，在训练样本时能够在考虑网络逼近行为的同时对噪声分布进行估计。而且 针对椒盐噪声模型构造了新的鲁棒误差函数，从而使算法本身的抗干扰性增强。实验结果表 明了该算法与传统BP 算法相比具有更好的滤波性能。(Abstract This paper presents a new maximum likelihood method based on impulse noise filter. In the traditional BP algorithm, the introduction of the maximum likelihood estimation, the training samples can also be considered acts of the network approach to estimate the noise distribution. Salt and pepper noise and model construction for a new robust error function, so that the enhanced anti-jamming algorithm itself. Experimental results show that the algorithm compared with the traditional BP algorithm has better filtering performance.)

说明：  在 matlab 中对无线网络的 ad-hoc 按需距离矢量(aodv)路由协议进行了仿真。 # # 先决条件 * matlab r2017b 或更新 # # 使用更改到该存储库的目录在 matlab。 把剧本叫做”主要”。 高级使用模拟通过网络的流量。 调用“ generatetraffic (packets)”通过网络发送指定数量的随机数据包。 调用“ generatetraffic (数据包，移动)”为数据包提供移动间隔。 对模拟交通进行分析，存储输出并提供给选定的分析函数。 每个图形并返回一个显示信息的图形的引用。(The simulation of ad-hoc on-demand distance vector aodv routing protocol in wireless networks is carried out in Matlab. # # prerequisites * Matlab r2017b or update # # with changes to the repository directory in Matlab. Call the script "the main" . Advanced usage simulates traffic through the network. A call to "generate tactical packets" sends a specified number of random packets over the network. Call "generate RAFFIC packet, move" to provide a migration interval for the packet. The simulation traffic is analyzed, the output is stored and provided to the selected analysis function. Each graph returns a reference to the graph that displays the information.)
