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 requires the sender through a coding system for pre-treatment data-coding, will be heard in the data decoding.
