二维FDTD的MATLAB的源程序，以直径为6cm的金属圆柱为例。(Two-dimensional FDTD the MATLAB source to a diameter of 6cm metal cylinder as an example.)

说明：  这个水印一般般利用DWT变换和DCT变换嵌入水印，加上了Arnold变换使图片水印的抗MP3压缩攻击有所提高。(The watermark in general as the use of DWT transform and DCT transform embedded watermark, coupled with the Arnold transform to image watermarking against MP3 compression attacks increased.)

matlab code 使用dibr 產生虛擬圖，使用實裡面有 readme，code 裡有說明如何使用。(dibr Matlab code to generate the virtual image, the use of solid inside the readme code, there are instructions how to use.)

这是一个LZW解压的matlab子函数程序和主函数，要结合我第一个上传的LZW压缩来看，这样有助于理解，效果很少明显，压缩率80 以上，不懂的跟我联系，我交你！！！我弄懂了！(It is a realisation of lzw decompression.Its compression ratio is beyond 80 .Its compression source is the first file which I have uploaded.If you have some questions,you can contact with me.)

8PSK信号调制，基于matlab源代码。并计算误码率(8 PSK modulation signal, based on the matlab source code. And calculate the error rate)

说明：  男声，女声，乐器声音频谱分析和傅里叶转换(Male, female, musical instruments, sound spectrum analysis and Fourier transform)

Simulacion de transmision por multiplexacion de division de frecuencia de cuatro audios.

运行源程序channel-coeff后，可以产生MIMO衰落信道，用I-METRA方法对信道衰落进行建模( After running the source channel-coeff, can produce MIMO fading channels, with I-METRA channel fading method for modeling)

使用MATLAB软件将三维图转化为二维图形实现。(Using the MATLAB software to three-dimensional images into two-dimensional graphics to achieve.)

说明：  pca主成分分析算法matlab源码，利用matlab实现pca算法。附带pca相关资料……(pca principal component analysis algorithm matlab source code, the use of matlab to achieve pca algorithm. Pca with information ... ...)
