The main parts of adaptive filter, the adjustable parameters of the digital filtering and adaptive algorithm, are as shown in Figure 1. Adjustable parameters digital filter can be FIR filters or IIR wave digital filter, and also can be cell-type digital filter. Input signal x (n) by the adjustable parameters digital filter form output signal y (n), it will be compared with the reference signal d (n) to form the error signal e (n). By some adaptive algorithm E (n) adjust filter parameters, to the end, it will make the e (n)’s mean square value to the minimum. Adaptive filter is a special Wiener filter which is able to automatically adjust itself parameters, in the design, it does not require prior knowledge of the input signal and the knowledge of the statistical properties of noise, it has gradually understanding of its own working process. Or estimates the necessary statistical characteristics, and automatically adjusts itself based on the parameters, reaches the best filtering eff
