光谱预处理源程序2

说明：  matlab实现的阶次分析算法，用于变转速机械故障特征提取，可运行，包含寻找脉冲时刻，等角度时刻，数字跟踪滤波，样条差值等步骤(The order analysis algorithm realized by Matlab is used to extract the fault features of variable speed machinery. It can be operated, including the steps of finding impulse moment, equal angle moment, digital tracking filtering, spline difference and so on.)

很经典的MELP的MATLAB算法仿真。从一个外国网站上下载，很棒(MELP is the classic algorithm of the MATLAB simulation. From a foreign website, great)

说明：  这是一个从音频信号里提取特征参量的程序，从事此方面的同志，不妨参考(This a signal from the audio extract features parametric procedures, engaged in this regard, the comrades might reference! !)

基于melp算法的语言编码传输，用于语言压缩传输(Speech coding transmission based on MELP algorithm)

MMSE语音降噪算法，使用维纳滤波器的方法，运算量适中，能实时处理(MMSE weiner noise reduction)

这里主要是压缩感知的贪婪算法，通过OMP来实现DOA的估计，主要应用在阵列信号处理领域。(Here compressed sensing greedy algorithm OMP, the main application in the field of array signal processing to achieve the DOA estimates.)
