维特比算法用于扩频信道译码，与Turboo码,卷积码，级联码构成编码系统-Viterbi Algorithm for spread spectrum channel decoding, and Turboo code, convolutional codes, concatenated coding system code constitute

利用哈夫曼编码进行通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求在发送端通过一个编码系统对待传数据预先编码，在接受将传来的数据进行译码。-use Huffman coding can be greatly improved communication channel utilization, shorten information transmission time and reduce transmission costs. However, this require

利用哈夫曼编码进行通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本，实现哈夫曼的编码译码-The use of Huffman coding to communicate can greatly improve channel utilization, shorten the transmission time information and reduce transmission costs, implementation Huffman encoding decoding

软判决译码，是信道编码方面很好的资料，ｃ语言代码实现！-Soft decision decoding, channel coding is very good information, c language code!
