The use of Huffman coding can greatly improve the utilization of channel, shorten the time of information transmission and reduce the transmission cost. However, this requires the transmitting end to be precoded through a coding system, and the data that will be transmitted at the receiving end is decode (Fu Yuan). For a duplex channel (that is, a channel that can transmit information bi-directional), a complete coding / decoding system is needed at each end.
