Weibull-distribution-test

对matlab的初学者也许有用， 特别是控制系统专业的使用者 一些讲义(right Matlab beginners might be useful, especially professional control system users some lectures)

关于cdma的直接序列扩频系统的经典编程，包括发射机，瑞利信道模型，接收机等的程序编写。(On direct sequence spread spectrum cdma classic programming, including the transmitter, Rayleigh channel model, receiver, etc. programming.)

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.

svm在matlab中的应用的一些程序以及说明(svm application in matlab some of the procedures)

说明：  采用db1基本小波来分解信号,比较第三层近似信号与原始信号,重构最大误差,比较第三层近似信号与原始信号.(used db1 to the basic wavelet decomposition signal, the third layer approximate comparison with the original signal signal, the largest reconstruction error Comparing the third layer similar to the original signal with the signal.)

通过像素复制放大或缩小图像实验，imgchang1函数为缩小图像，imgchang2函数为放大图像(By pixel replication zoom in or out experiments, imgchang1 function to narrow the image, imgchang2 function enlarge image)

压缩感知源代码，观测矩阵采用哈达吗变换。很好的入门代码(Compressed sensing the source code, you transform observation matrix using Hada. Good entry code)

小波包程序，能够对信号进行特征提取，对初学者有用。(This is a wavelet packet program, which is useful for the Beginners. )
