说明：  利用哈夫曼编码进行住处通讯可以大大提高信道利用率,缩短住处传输时间,降低成本,但是,这要求在发送端通过一个编码系统将传输的数据预先编码,在接收端通过一个译码系统对传来的数据进行译码(复原),对于双向传输信息的信道,每端都一个完整的编码译码系统,试为这样的住处收发站写一个哈夫曼友的编码译码系统.
(Huffman coding for home use can greatly improve the communication channel utilization, shorten the residence transmission time and lower costs, however, and this requires the sending end through a coding system will be pre-encoded data transmitted in the receiving end through a decoder system Decoding the data came (to recover), for a two-way channel to transmit information, each side have a complete codec system, test for such a residence transceiver stations to write a Huffman Friends codec system.)
