数据仓库中，数据挖掘的一个程序，用MATLAB编写，好用！(Data warehouse, data mining, a procedure, using MATLAB to prepare, easy to use!)

将周期图、自相关、协方差、改进协方差、Burg五种谱分析法封装为函数，并调用之对三个不同的信号源进行谱估计。(Encapsuler 5 methods of spectrum uation (Periodogram, COR, COV, MCOV, Burg) as functions, and use them to do frequency uation of three different signals.)

此程序代码，可以在matlab上仿真，滤掉高频信号(This code, Matlab simulation, filter out high-frequency signal)

用matlab编写的最近邻域的数据关联，采用kalman滤波实现(Associated with the most recent data prepared matlab neighborhood, using kalman Filtering)

等间距线性阵列，阵元数M=8，阵元间距d= λ /2，等幅加权，目标方位φr =0°。产生空间白噪声矢量（复高斯分布）。 设阵列信号矢量元素s(m)=exp[j mψr]，其信号幅度为1，该阵元接收机附加的高斯噪声为n(m)=nmr+jnmi，其中实虚部均为独立同分布N(0, σ2)的高斯随机数，则该通道合成信号x(m)=s(m) + n(m)，其中信噪比为： SNR = 10 lg[1/(2σ2)] = – 3 – 10 lg(σ2) (dB) (The spacing of the linear array, and the array element number M = 8, the array element spacing d = λ/2, equal amplitude weighted target azimuth φR = 0. Space generated white noise vector (complex Gaussian distribution). Let array signal vector elements s (m) = exp [j mψr], the signal amplitude, the element receiver additional Gaussian noise n (m) = nmr+jnmi which the real and imaginary parts are independent and identically distributed N ( Gaussian random numbers of 0, σ2), the channel the synthesis signal x (m) = s (m) the PPLS n (m), where SNR is: SNR = 10 lg [1/(2σ2)] =- 3- 10 lg (σ2) (dB))
