dipum_images_ch05 matlab 编程实例(dipum_images_ch05 matlab Programming Example)

对TD-SCDMA做了一个简化的仿真，主要包括QPSK调制，扩频。结果有误比特率的值和眼图，绝对可用！(A simplified simulation of TD-SCDMA, including QPSK modulation, spreading. Result of the value of the bit error rate and eye diagram, absolutely free!)

一本极少非线性有限元基本理论和程序实现的经典教材(An intruoduction nonlinear finite element method )

用MATLAB产生高斯白噪声的算法。该历程用的是产生标准正态分布的高斯白噪声(Use MATLAB to create Gaussion White Noise)

基于DWT及DCT的数字水印的代码，该改代码是分开形式给出，具体结果自己可以运行试试，很不错的(key word is DWT AND DCT ,if you are interested in it ,you can call me ,we can talk about it.)
