A DATA INTERACTION METHOD, SYSTEM AND DATA TRANSCEIVER DEVICE

摘要

A data interaction method, system and data transceiver device, for solving the existing problem that the symbol number that can be delivered in the CTS is reduced and the bandwidth utilization rate is low which is caused when ensuring signal be decided correctly by enlarging symbol cycle. The data interaction method comprising: the transmitting end transmits frame pieces piece by piece, the frame piece contains a valid data segment of the data frame and a start delimiter and a end delimiter at both ends of the data segment; and the receiving end determines the frame piece length according to the start delimiter and the end delimiter, and receives the valid data segment between the both delimiters. The data transceiver device comprises data frame segment intercepting/assembling element, delimiter add/delete element and transceiver element. The method according to the present invention needn't compensating the receiving data decision error caused by receiving time asynchrony through enlarging the width of single symbol in CTS and reduces the system bandwidth occupied by CTS.
