< 超宽带无线电基础>>的第八章原代码,主要用于超宽带无线电信号波形的产生信道估计\扩频通信等等,内容非常丰富.()

图像增强处理的方法有很多，本程序采用反锐化掩膜法增强图像，并与直方图均衡法增强图像的效果进行对比。(There are alot of methods of Image enhancement processing.this program is based on the Anti sharpen mask method.Then contrast the result with Histogram equalization method. )

Input: x: input image ru, rd: amount of extension, up and down, for rows cl, cr: amount of extension, left and rigth, for column extmod: extension mode. The valid modes are:主要用于图象处理和模式识别( Input: x: input image ru, rd: amount of extension, up and down, for rows cl, cr: amount of extension, left and rigth, for column extmod: extension mode. The valid modes are:)
