- 把消息转换成电信号。信源可分为模拟信源和数字信源。区分模拟信号和数字信号的准绳是看其取值是连续的还是离散的，而不是看时间。 信源编码：主要是利用信源的统计特性，解决信源的相关性，去掉信源冗余信息，提高系统有效性的目的。 信道编码：保证通信系统的传输可靠性，克服信道中的噪声和干扰。 调制：其主要目的是使经过编码的信号特性与-The message into electrical signals. Source can be divided into analog source and

A-new-adaptive-median-filter
- 一种新的自适应中值滤波方法。将3 x3窗口中心的极值点作为候选噪声点，若候选噪声点仍然是7 x7窗口的极值点，则该点即是噪声点。若以噪声点为中心的3 x3滤波窗口的中值不是噪声，则噪声用中值替换。重复以上过程，直到没有噪声点被替换。如果图像中仍然存在人的噪声团块，则噪声用相邻的三个信号点的灰度均值替换。实验结果表明，该方法能够有效去除脉冲噪声，并在抑制噪声的同时很好地保护图像的细节。-A new adaptive median filter. The extreme points of the
