该程序是一个振荡相位噪声模型。相位噪声是衡量频率标准源(高稳晶振、原子频标等)频稳质量的重要指标，随着频标源性能的不断改善，相应噪声量值越来越小，因而对相位噪声谱的测量要求也越来越高。(The program is a model of phase noise oscillator. Phase noise is a measure of frequency standard source (high stability crystal oscillator, atomic frequency standard, etc.) an important indicator of the quality of the frequency stability, with the frequency standard source performance continues to improve, the corresponding noise value smaller, and thus the phase noise spectrum of the measurement requirements higher and higher.)

说明：  对标准卡尔曼滤波方法中野值对其滤波精度的影响，提出了基于M估计的野值 处理方法。这种方法不仅可以去除单个野值的影响，而且在野值成片出现时还能很好地保持滤波 稳定性。通过仿真验证了该方法的有效性。(Their filtering accuracy on the standard Kalman filtering method outliers, outliers based on M-estimation approach. This method can not only remove the impact of individual outliers, and opposition values ​ ​ into the film appears to keep the filter can be very stability. The effectiveness of the method is verified by simulation.)

用MATLAB写的，用Prim算法找出图中的最小支撑树，文件中有例子，有计算的结果，一看便懂。(Written in MATLAB, with the minimum support tree in the Prim algorithm to find a figure, file example, with the result of calculation, a see will understand.)

The following code implements a kernel wiener filter algorithm in MATLAB.The algorithm dependes on the eigenvalue decomposition, thus only a few thousand of data samples for training dataset is applicable so far.
