用于信号处理的MATLAB基本操作，离散时间的信号，典型序列(MATLAB for the basic operation of signal processing, discrete-time signal, a typical sequence)

这是一个求离散时间序列的功率谱的程序，是通过全波傅里叶变换来求的(This is a demand of the power spectrum of the discrete-time sequence program is through the full-wave Fourier transform to seek)

混沌模型logistc映射程序，描述昆虫变化的经典数学模型——虫口模型(Chaos Model logistc mapping procedures, changes in the classic description of insects mathematical model- Population Model)

16QAM的调制，它把输入的二进制数据以查找表的方式进行映射，从而提高信息传输率。(16QAM modulation, it is the input of binary data to find a way to map the table to enhance information transfer rate.)

说明：  S变换是较新的时频分析工具，甩在低频段有较宽的的时间窗，以获得较高的频率分辨率；而在高频段时间窗窄，以获得较高的时间分辨率。这里给出了ST和GST（广义S变换）的函数。(S transform is a relatively new time-frequency analysis tool, left in the low frequency band has a wide time window in order to obtain higher frequency resolution and in high-frequency narrow time window in order to obtain higher temporal resolution. Here are given ST and GST (generalized S transform) function.)

Normal ECG test taken on 250 Hz (sampling frequency) You can use in order to obtain (and compare) the stress (from HRV) (compare with ecg stroop & ecg matematica )

这个例子将产生并显示pi/2 DQFSK系统中的一些重要信号，仿真这个系统并产生图形输出的MATLAB程序在文件夹中给出。在MATLAB的命令提示符下输入程序名c8-pi4derno后，会绷现一个菜单，用户可通过这个菜单选择以下七个选项中的一个（产生一个图形后，击空格键会显示菜单以便作另一个选择） 1.滤波前的pi/4 DQPSK信号星座图 2.滤波前的pi/4 DQPSK眼图- 3.滤波后的pi/4 DQPSK信号星座图 4.滤波后的pi/4 DQPSK眼图 5.滤波前的同相和正交信号 6.滤波后的同相和正交信号 7.退出程序(返回MATLAB命令提示符) 读者应该仔细研究文件夹中的内容，因为它阐明了很多常见的后处理过程，而且，产生各种图形的代码可用于其他仿真程序的后处理器。 (It is very difficult to describe the MATLAB procedure in english.)

提出了一种改进的独立分量分析方法对脑电信号进行去伪迹消噪，取得了相当不错的效果(An improved method of independent component analysis to EEG artifact noise cancellation, very good results achieved)
