算术编码与译码的matlab程序 信息论 通信 (matlab)

说明：  HDB3码的编码，图形，功率谱密度。用于通信原理教学等(Code HDB3 coding, graphics, power spectral density. Communication Theory for teaching)

刘金琨老师书上很好的滑模程序,很详细很有代表性。(Liu Jinkun teacher good book sliding mode program.)

用直接周期图法，分别对有噪声和无噪声的信号进行谱估计。(Direct cycle diagram, respectively noise and noise-free signal spectrum estimation.)

粒子滤波算法；粒子滤波算法源于Montecarlo的思想，即以某事件出现的频率来指代该事件的概率。因此在滤波过程中，需要用到概率如P(x)的地方，一概对变量x采样，以大量采样的分布近似来表示P(x)。因此，采用此一思想，在滤波过程中粒子滤波可以处理任意形式的概率，而不像Kalman滤波只能处理高斯分布的概率问题。他的一大优势也在于此。(these codes are particle filter resources codes which solve non-linear estimation problems.I wish that it is helpful to some people.I am glad to share it with others. )

Simpson integration method(1/3)

基于超平面 欠定盲分离源信号的混合矩阵的估计(underdetermined Blind Source Separation)

现代信号处理大作业2，实现WV分布并画出3D图，指出信号项和交叉项，需要用到tftb-0.2工具箱(2 large modern signal processing operations to achieve WV distribution and draw 3D maps, points out items and cross-term signal is needed for tftb-0.2 Toolbox)

This is code for OFDM

带通滤波函数，故障诊断时采集振动信号后对信号进行滤波后处理。(The signal is filtered after the signal is collected in the fault diagnosis)
