程序实现了基于MATLAB的pi/4 QPSK的仿真,系统在相同条件下，对加噪声和没有噪声的情况，分别画出了它的眼图分析其性能，及已调制信号的时域波形和频谱。(The program realizes the simulation of pi/4 QPSK based on MATLAB. Under the same condition, the system draws its eye diagram to analyze the performance of the noise and no noise, and the time domain waveform and spectrum of the modulated signal .)

music算法：矩阵特征空间分解，在空间谱域求取谱函数最大值，其谱峰对应的角度即是来波方向角的估计值。(music algorithm: Matrix feature space decomposition, in the spatial spectral domain to strike a maximum spectral function, its spectral peaks corresponding to the angle that is DOA angle estimate.)

说明：  图像处理应用。对LINA图的直方图提取等(Image processing applications. Histogram graph of extraction LINA)

说明：  利用Fisher线性判别来进行男女分类（里面已经有了男女的数据）(Using Fisher linear discriminant for classification of men and women (which already have the data for men and women))

说明：  MATLAB 神经网络用于数字识别源程序 手写数字识别(MATLAB neural network for digital identification of the source handwritten numeral recognition)

ABS建模仿真 应用matlab里simulink模块实现(ABS modeling and simulation applications matlab simulink module)
