A simulink model for chaotic Gyrostat system

common movement of inertia calculation of inverted wedge

说明：  通信原理课本中的一些实例代码，方便大家使用(Communication principles in the textbook of some examples of code, easy to use)

说明：  本程序利用平均周期图法（bartlett法）对信号进行功率谱估计，指定输入响应信号，根据实际情况调整参数，输出功率谱图(The program uses the average periodogram method (bartlett method) on the signal power spectrum estimation, specify the input response signal, adjust the parameters according to actual situation, the output power spectrum)

TWO STATE SEMI MARKOV LMS CHANNEL MODEL

用matlab语言实现32阶FIR滤波器，并实现气频域和时域仿真(Matlab language with 32-order FIR filter, and to achieve air frequency domain and time domain simulation)

动态PCA方法，引入动态时间l，考虑变量本身的时序自相关性，同时还分析变量之间的时序相关性,把PCA方法应用到动态数据矩阵。 (Dynamic PCA method, introducing dynamic time l, consider the timing of the variable itself autocorrelation, also analyzed the correlation between the timing variables, the PCA method is applied to dynamic data matrix.)
