中文说明：维纳（Wiener）是用来解决从噪声中提取信号的一种过滤（或滤波）方法。这种线性滤波问题，可以看做是一种估计问题或一种线性估计问题。这是包括维纳滤波器FIR和IIR的算法。
English Description：
Wiener is a filtering method to extract signal from noise. The linear filtering problem can be regarded as an estimation problem or a linear estimation problem. This algorithm includes Wiener filter FIR and IIR.
