sparfilt
优点:1.对于信噪比高的信号滤波效果好;
% 2.对于边沿的保护强过阈值滤波,不会产生阈值滤波情况下的过于平滑与Gibbs现象。
%缺点:1.由于对边沿信号没做任何处理,所以边沿可能会有脉冲噪声保留下来;
% 2.计算相关系数中,如果计算出来的小波系数点位置偏差大,则相关系数计算受影响;
% 3.需要迭代运算,迭代的噪声能量阈值选取很重要,这里以开始段无信号处估计噪声;
% 4.需要迭代运算,所以运算量比阈值法大;
% 5.受分解层次影响,在大尺度上小波系数点位置偏差更大,相关系数计算不准确。
%需要具体调整的地方:1.分解的尺度;()

ARMODEL
功率谱估计的应用范围很广,在各学科和应用领域中受到了极大的重视。在《现代信号处理》课程中讲述了经典谱估计和现代谱估计这两大类谱估计方法;经典谱估计是基于傅立叶变换的,虽然具有运算效率高的优点,但是频谱分辨率低同时旁瓣泄漏严重,对长序列有着良好的估计。为了克服经典谱估计的缺点,人们开展了对现代谱估计方法的研究。现代谱估计是以随机过程的参数模型为基础的,有最大似然估计法、最大熵法、AR模型法、预测滤波器法。现代谱估计对短序列的估计精度高,同经典谱估计互为补充。在认真学习了现 代谱估计方法后,我选择了现代谱估计中的AR模型法的仿真作为题目。下面给出AR模型的相关理论和仿真实现。(Power Spectral Estimation of very extensive, in all disciplines and fields of application of a great deal of attention. The "modern signal processing" on the curriculum of classical and modern spectral estimation spectrum is estimated that the two types of spectrum estimation method; Classical spectrum estimation is based on Fourier transform, although high computing efficiency advantages, but also low-resolution spectrum Sidelobe serious leakage of long sequences have good estimates. In order to overcome the classic shortcomings of the spectrum estimation, there have been a pair of modern spectral estimation methods. Modern spectral estimation is the random process model parameters based on the maximum likelihood estimation, maximum entropy method, AR model, forecast filter. Spe)
