自适应预测法在去噪声中的应用

在信号检测中，突变点和脉冲点的检测尤为重要，本文首先用多项式预测法找出输入信号的突变点和脉冲点。并证明了预测因子之和为１．文中将时装城的一维信号看成有产品，，上突变点信号按谱系分成多类，然后对每一类用多项式预测法，即左预测和右预测去除脉冲噪声和白噪声，该方法能有效的保护信号的突变现象。

Adapted Prediction Method for Noise Attenuation

In detection of signals,detection of jump points and impulse points are more important.In this paper,we find out the jump points and impulse points of the signal.We can regard the one dimensional signal as ordered samples,to classify the signal by jump points.In every classification,We derive a polynomial predictor,namely left prediction and right prediction,to attenuate white noise and impulase noise.The method can retain the signal jump phenomenon effectively.
