Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

一个坐标系转换的类，参考系：WGS-84椭球体参数；功能：笛卡尔坐标系、大地坐标系、站心地平坐标系（线坐标形式）、站心地平坐标系（极坐标形式）之间的互相转换。(A coordinate transformation class reference system: WGS-84 ellipsoid parameters Function: Cartesian coordinates, geodetic coordinate system, Station Local coordinate system (line coordinates), Station Local coordinate system (polar form) of conversion between each other.)

这是用MATLAB编写的模拟退火算法求解背包问题的程序(This is prepared using MATLAB algorithm simulated annealing procedure for Knapsack Problem)

说明：  曲线拟合的程序，包括点数据。刚接触matlab,请大家多多指教。(Curve fitting procedures, including data.刚接触matlab, please everyone exhibitions.)

说明：  基于短时能量 短时过零率 自相关函数的语音清浊分类算法(Zero based on short-term rate of short-term energy autocorrelation function of speech voicing classification algorithm)

SVM是分类器对于它的准确性还有过拟合性都有很成熟的改进 关于SVM函数拟合 (SVM is a classifier for its accuracy still has a very mature over-fitting of improved function fitting on SVM)

this simulation is a way for watermarking and steganography with j-uniward

这是本关于图像出处理的书籍，里面有很多例子，并且每个例子都给出了MATLAB程序(This is a book about image processing books, there are many examples, and examples of each are given MATLAB program)

This is the matlab code of Regularized Common Spatial Pattern (R-CSP) algorithm.
