说明：  卡尔曼滤波器是用前一个估计值和最近一个观察数据估计信号的值，他是用状态方程和递推的方法进行估计，本例用来追踪一个5阶的FIR不确定的滤波器系数。(Kalman filter is to use the previous estimate and the most recent observation data to estimate the value of the signal, he is using the state equation and recursive estimation methods, in this case is used to track a 5-order FIR filter coefficients of uncertainty.)

Floyd的Matlab教程，很简单。。 几行代码而已。(Floyd' s Matlab tutorial, very simple. . A few lines of code.)

利用自适应陷波器来消除通信系统中的工频干扰。重点从LMS算法的步长因子、信号与干扰的频率差、参考输入的幅值和相位等几个方面讨论单频陷波器的滤波效果。另外，还以双频为例，讨论了多频级联型陷波器的特性，证实了经过两次滤波后，信号可被真实的恢复出来，且误差收敛趋于稳定。(The use of adaptive notch filter to eliminate the communication system frequency interference. LMS algorithms focus from step factor, the frequency difference signal and interference, refer to the input amplitude and phase of discussions on several aspects of single-frequency notch filter of the filtering effect. In addition, in order to dual-band, for example, discussed the multi-frequency cascade notch filter characteristics, confirmed the filtered twice, the signal can be restored out of true, and the error convergence stable.)
