倾角传感器的小波阈值消噪

针对非平稳信号进行小波阈值消噪方法,提出了一种将广义交叉确认（GCV）规则和遗传算法结合的新方法,利用这种方法,可以求得近似最佳阈值。接着,将方法应用到倾角传感器信号消噪中,取得到了很好的效果。

Noise Elimination of Angle Sensor by Wavelet Threshold

This paper proposes a new method which combines a generalized cross validation （ GCV） with genetic algorithms. This method aims at eliminating noises for non-stationary signals by using the wavelet threshold. With this method,an approximate optimal threshold value can be obtained. Then,the method is applied to the angle sensor signal to eliminate its noise. Finally,good effects are achieved.
