集成了不少常用的图像融合评价和检测的标准的matlab代码实现( English Spanish Arabic Integrates many commonly used image fusion evaluation and testing of the standard matlab code)

watterson信道matlab仿真,瑞利衰落。。。。(This example shows how to simulate High-Frequency (HF) ionospheric channels, based on the models described in Recommendation ITU-R F.1487. In particular, it shows how to simulate the general Watterson channel model, and other simplified channel models used in the quantitative testing of HF modems. It makes use of the Rayleigh multipath fading channel object and the Gaussian and bi-Gaussian Doppler structures from Communications System Toolbox.)

OFDM通信系统仿真模型 包括编码，调制，IFFT，上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码模块 最后验证了系统设计的可靠性 是通信理论OFDM技术仿真实例(OFDM communication system simulation models, including coding, modulation, IFFT, and down conversion, Gaussian channel model, FFT, PAPR suppression, various synchronization, demodulation and decoding module final validation of the reliability of the system design is communication theory simulation OFDM technology)

its the data base loading file in matlab

惠更斯-菲涅尔衍射计算，非常不错，简单易行。(Huygens- Fresnel diffraction calculations, very good, easy.)

explore the r g b components of a given image. see different images according to the r g b component chosen

对图像数据做DCT变换及DWHT变换的示例程序，在matlab7下运行正常(Done on the DCT transform of image data and transform DWHT example the procedures in the normal run matlab7)

FOR IMAGE RETRIVAL USING WAVELET01

一种改进的变步长归一化算法的研究，对比归一化算法，有了比较好的改善(An improved variable step length normalization algorithm research, contrast normalization algorithm, a better improvement )
