摘要
在信号去噪声中,要同时去除脉冲噪声和白噪声,有一定的困难本文研究了左预测和右预测,及中心平滑法,并证明了中心平滑法中的两个限制条件提出了预测混合中心平滑法去噪分析了该方法的根信号特征及统计特性并通过摸拟试验检验了该方法。
In noise attenuation, it is difficult to reduce impulse noise and white noise at same time. In this paper, we study the left prediction, right prediction and middle smoothing, and prove two contraints conditions. We give the prediction hybrid and middle\|smoothing(PHS) method to attenuate noise. We also analyze the method's root signal structure and statistical property. At last, we employ some examples to check the PHS method. The result shows that the method is effective.
