一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

上传的matlab程序是股票市场的市场冲击成本程序，欢迎大家下载查阅！(the file is the matlab program of Impact Cost! )

论文使用一种经典的特征提取方法—主成分分析法（PCA）进行特征提取，其基本思想是降维。降维后的数据除了计算工作量减少之外不会减少原始数据所包含的有效信息量。(This paper use a classical method for feature extraction—Principal Component Analysis(PCA)with the basic idea of dimensionality reduction(it still contains all valid information).)

MATLAB实现循环码的编码与解码，Cyclic code encoding and decoding based on MATLAB(Cyclic code encoding and decoding based on MATLAB)

基于Matlab模拟实现，是基于Matlab的仿真，对软件的要求很高，要求用Matlab实现对信号的调制解调和对信道的模拟。(Matlab-based simulation implementation is based on the Matlab simulation, the software requirements, demanding to achieve with Matlab signal modulation and demodulation and analog channels.)

地震勘探中常用的marmousi模型，用matlab绘出的原始图像，用线性插值，领近插值，双线性插值等多种差值方法来对marmousi模型进行处理(Marmousi commonly used in seismic exploration model of the original image using matlab plot, using linear interpolation, brought nearly interpolation, bilinear interpolation method for a variety of difference to be processed for marmousi model)

ofdm精同步算法实现，包含slot_test和其他8个模块(ofdm fine synchronization algorithm, including slot_test, and other 8 modules)

四种（横线形 竖线形 十字形 方块形）中值滤波(Four kinds of (horizontal cross-shaped vertical-shaped box-shaped), the median filter)

一个matlab遗传算法源程序,自己找来的，原代码有少许错误，本人都已更正了，调试运行都通过了的。对于初学者，尤其是还没有编程经验的非常有用的一个文件. (A genetic algorithm matlab source code, could think of, the original code was flawed, I have been corrected, debugging and running through the of. For starters, in particular, no programming experience is very useful to a file.)
