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,试验结果说明了该方法是切实可行的 In the de-noising of the signal, it is difficult to remove both the impulse noise and the white noise at the same time. In this paper, we study the left and right prediction and the center-smoothing method and prove that the two constraints in the center-smoothing method propose the prediction mixing center The root signal characteristics and statistical properties of this method are analyzed by the smoothing denoising method. The method is tested by the simulation test. The experimental results show that this method is feasible
