State Space Simulink Model with Two variables.

说明：  基于matlab的编程，信道仿真的，很好很强大(Matlab-based programming, channel simulation, very good very strong)

核密度估计，可以刻画变量的时间演进动态性，可以反映变量在时间上的变动的整体性( Kernel Density Estimation )

yangjianchao将稀疏编码引入到超分辨率重建的文章(Yangjianchao will be introduced to the sparse coding super-resolution reconstruction)

DOA estimation for uniform linear array based on music algorithm

信号的一些时域指标计算，有效值，峰峰值，峭度，能量，倾斜度等(Calculation, effective value, some indexes of time domain signal peak, kurtosis, energy, gradient)

this file has codes that describes how to ccmpute the signal spectrum , the power spectrum, how to calculate the autocorrelation sequence of a signal, how to calculate the autoregressive coeffecients of a signal,and how to reduce the noisy elements in a speech sample.

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)

包含轴承故障数据，来源于MFPT（Machinery Failure Prevent Technology）论坛，分四组训练数据和测试数据； 数据可直接做频谱分析，效果很好(contain bearing faults data sets, 4 train datas and 4 test datas, can be used for FFT/envespectrum analysis, and you will get perfect effects.)

详细介绍了LMS自适应波束形成算法,适合初学波束形成的人群(Details of the LMS adaptive beamforming algorithm, suitable for beginners crowd beamforming)
