利用哈夫曼编码进行通信可以大大提高通信信道利用率,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将传输数据预先编码;在接收端将传来的数据进行译码(复原)。对于双工信道(即可以双工传输信息的信道),每端都需要一个完整的编/译码系统。为这样的信息收发站设计的一个哈夫曼编/译码系统。 (2-use Huffman coding communication can greatly enhance communication channel utilization, reduced transmission time, and lower transmission costs. This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.
