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，在接收端将传来的数据进行译码（复原）。-The use of Huffman coding can greatly improve the communication channel utilization, reduce the information transmission time, lower transmission costs. However, this requires the sending end through a coding system for pre-treatment of mass data encoding, will be heard at the receiving end of the data decoding (recovery).
