本文件是有关于QPSK仿真的matlab源码。(This document is QPSK simulation on matlab source.)

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.)

Matlab to text file conversion

this is the program for finding peak power in ofdm using selective mapping

说明：  这是基于matlab下的数字信号处理示例，包括信号、系统和系统响应的实现等(These are some digtal signal processing examples based on the matlab. And these include filter ,matrax algthrom,and so on......)

matlab实现通信系统中信道的仿真，其中包含了最基本的matlab产生各种信道的代码，并有详细的说明(matlab simulation of communication systems the channel, which contains the most basic of matlab code to generate a variety of channels, and a detailed description of)

利用matlab写成的窄带噪声发生，含噪脉冲信号进行相关检测,包括数据分析、绘图等等。( Using matlab written narrowband noise occurs, Noisy pulse correlation detection signal, Data analysis, plotting, etc..)

说明：  图像的双线性插值放大算法中，目标图像中新创造的象素值，是由源图像位 置在它附近的2*2 区域4 个邻近象素的值通过加权平均计算得出的。 双线性内插 值算法放大后的图像质量较高，不会出现像素值不连续的的情况。然而次算法具 有低通滤波器的性质，使高频分量受损，所以可能会使图像轮廓在一定程度上变 得模糊。 (Bilinear interpolation algorithm to enlarge the image, the target image in the newly created pixel value is determined by the source image position in its area near the 4 2* 2 the value of neighboring pixels calculated by the weighted average. Bilinear interpolation algorithm to enlarge the image quality after the high pixel value does not appear the situation is not continuous. However, sub-algorithm has low-pass filter nature of the damage to the high frequency components, it may make the image contour to some extent become blurred.)

matlab编程中常用的一些程序，如一维单尺度及多尺度小波分解与重构。(matlab programming of commonly used procedures, such as a single-scale and multi-dimensional scale wavelet decomposition and reconstruction.)

实现离散卷积的源代码 里面集成了可运行的全部代码(Discrete convolution code realization)
