考虑阴影效应，多普勒频移等的影响，用于描述瑞利衰落信号的信号特征(Take into account the shadow effect, Doppler shift, etc., used to describe the signal characteristics of the Rayleigh fading signal)

a pre-processing box for standard Microarrays data set

文章的代码主要讲述椭圆型方程五点差分格式。用MATLAB软件来实现，大大提高了算法的精确度。(The code article focuses on five difference scheme for elliptic equations are considered. Use MATLAB software to realize, greatly improve the precision of the algorithm.)

It can be easily seen the above analysis that the shootthrough duty ratio is always constant. This can be reconfirmed a different perspective below

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印(Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection)

说明：  matlab代码功能实现图像的距离变化，已经通过调试成功！(matlab code image of the distance function changes have been adopted successfully debug!)

说明：  介绍jade的matlab代码，保证准确，另外有一幅图像是sar图像(Jade' s matlab code introduced to ensure the accuracy, another image is sar image)

用于语音信号MFCC特征提取的matlab程序(matlab program of MFCC feature extraction for speech signal )

SC-FDMA性能分析，及与FDMA误码率比较(SC-FDMA performance analysis, and compared with FDMA for BER)
