自适应神经网络模糊技术的噪声抵消方法

Noise Cancellation by Using Adaptive Neuro-Fuzzy Inference System

利用自适应神经网络模糊推断系统可以抑制噪声 ,即从信号和噪声混合中提取信号 ,这种方法适用于有参考噪声的情况。正好适用于水动力噪声试验设备 ,其中背景噪声强 ,而且可以得到比较纯净的背景噪声作为参考噪声。这里给出了噪声信号在背景噪声中提取噪声信号的模拟例子。

In this paper,the noise cancellation is completed by using Adaptive Neuro-Fuzzy Inference System,which fits the case where there is a reference noise.The method means extracting signal from mixture of background noise and signal.The method can be applied to the hydrodynamic noise testing facilities where there is stronger background noise and getting rather pure background noise as reference noise.Finally,a simulative example is given, which is extracting noise signal from mixture of noise signal and background noise.
