Coding

利用游程编码和哈弗曼编码实现灰色图片的压缩和解码，压缩比可达15倍(Using run-length encoding and Hafu Man Coding and decoding of gray image compression, the compression ratio up to 15 times)

说明：  这是一个基本的CDMA系统的调制与解调系统。包括随机信号的产生，调制还有相应的解调。(This is a basic CDMA coding and decoding system, it includes random signal generator and coding and decoding modules )
