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。这要求在发送端通过一个编码系统对待传输预先编码，在接收端将传来的数据进行译码。对于双工通道（即可以双向传输信息的信道），每端都需要一个完整的编/译码系统。试为这样的信息收发站写一个哈夫曼码的编/译码系统。(功能非常完全)-The use of Huffman coding can greatly improve the communication channel utilization, reduce the information transmission time, lower transmission costs. This requires the sending end through a coding system to treat pre-transmission encoding, the receiver will decode the data came from. For duplex channels (that is two-way transmission of information channel), each client requires a full encoder/decoder system. Test for such information transceiver station to write a Huffman code encoder/decoder system. (Very incomplete)
