说明：  程序使用说明： 1、软件应用平台：Matlab6.5或更高； 2、打开方法： 将文件所在目录设为工作目录，然后打开wavlet.fig,在noise提示框下输入噪声强度，在0-0.1之间（不能为零）。 然后点process按钮，就会显示实验结果，包括原图像，加噪图像，去噪图像的对比以及当前的psnr值。 wavlet.m是程序文件。 程序内容写在在程序的注释里。 阈值的更改没有实现可视化，在源程序中可以改。(Procedure for use: 1, Software Platform: Matlab6.5 or higher 2, open the way: the file directory set the working directory, then open the wavlet.fig, the noise boxes, enter the noise level, in the 0-0.1 between (not zero). Then process the button, it will show the experimental results, including the original image, noise image denoising image contrast and the current psnr value. wavlet.m is the program file. Program content in the program notes written inside. Threshold changes are not visualized in the source program can be changed.)

QPSK调制解调仿真 从基带信号产生——IQ映射——调制——信道加噪——解调——判决及反映射——接收信号输出，每个步骤都画出了图形。 (QPSK modulation and demodulation simulation generated from the baseband signal- IQ Mapping- Modulation- channel plus noise- demodulation- judgment and reflect radio- reception signal output, each step to draw the graph.)

这个程序用来模拟windows计算器,为薜定宇老师<<科学运算语言MATLAB5.3程序设计与应用>>的习题而做(It is suitable for beginners to master matlab deep into the second developed a good teaching examples of great reference value)

使用高阶累积量对MPSK信号进行调制识别，结合PCA的尺度不变特征变换(SIFT)算法，这是一个好用的频偏估计算法的matlab仿真程序。( Using high-order cumulants of MPSK signal modulation recognition, Combined with PCA scale invariant feature transform (SIFT) algorithm, This is a useful frequency estimation algorithm matlab simulation program.)

本文首先推导出过采样滤波器组精确重构的条件, 由于此时所需的约束条件数比临界采 样时少, 因而可以设计出频域衰减特性更好的滤波器组(This paper is derived through sampling filters of exact reconstruction of conditions, due to time constraints required for critical extraction ratio When a small sample, so you can design a better frequency filter attenuation characteristics)

《Matlab编程_第二版》对于初学者来讲是一份不错的资料 (" Matlab programming _ the second edition of" speaking for beginners is a good information)

PAPR Reduction based on a Modified PTS with Interleaving and Pulse Shaping method for STBC MIMO-OFDM System. It is with GUI. Using GUI we can see comparison with number of sub carrier, sub-block and over sampling factor as well BER plot comparison of normal and with PTS technique. You need to run MIMO_OFDM_with_PTS.m Note: Do not delete or rename amy file and place all the files in one single folder because some are functions which are called in GUI code.

采用遗传算法和三次样条插值法对已给数据进行拟合，得出最优取点方案(Genetic algorithm and cubic spline interpolation method is to fit the data, obtain optimum take-point program)
