这是我在学习过程使用到的一些程序，希望对大家有所帮助!(This is what I used in the learning process some of the procedures, I hope all of you to help!)

基于matlab的直接序列扩频通信系统仿真，给出了扩频通信的整个流程(Simulation of direct sequence spread spectrum communication system based on MATLAB, the whole process of spread spectrum communication is given)

关于柯西分布的matlab工具包，包括概率分布函数，反函数等(On the Cauchy distribution matlab toolkit, including the probability distribution function, inverse function, etc.)

这是利用二维小波分析对含高频噪声的图像进行消噪的例程，这里采用的是小波分解系数阈值量化法，(This is the routine use of two-dimensional wavelet analysis denoising images with high-frequency noise, the wavelet coefficients threshold quantization method used here,)

刺激呈现后，脑血流的功能磁共振信号到底是怎样的。如何将实验设计的时间序列模拟出相应的磁共振信号(After the stimulus presentation, functional magnetic resonance imaging of blood flow signal is what in the end. How will the time series of experimental design to simulate the magnetic resonance signals corresponding)

将图像的灰度进行均衡化，并与matlab自带的均衡法进行比较！(this programe is designed to histeq the image! And this algorithm has been compared to the histeq function in the matlab)

说明：  生成C/A码的小程序，还可以计算自相关性(Generated C/A code small programs can also calculate the autocorrelation)

程序将一年中的天数转换到相应的月份及日期。适用于TLE数据中的日期转换。程序不用if语句，简单易懂高效。输入参数可以是数组形式。(The program will convert the number of days in a year to the corresponding month and date. TLE data for the date conversion. Program without the if statement, straightforward and efficient. Input parameters may be matrix form.)

粒子群优化是一种新兴的基于群体智能的启发式全局搜索算法，粒子群优化算法通过粒子间的竞争和协作以实现在复杂搜索空间中寻找全局最优点。(Particle swarm optimization is a new global search heuristic algorithm based on swarm intelligence, particle swarm optimization algorithm by particle competition and collaboration to achieve to find the global optimum in a complex search space.)
