The design and implementation of the unidirectional data transmission equipment based on 802.11 physical frame

摘要

With the rapid development of wireless network, people begin to require more on the reliability of data transmission, especially on the communication methods that can be applied under special condition. This paper usages the transceiver chip which is in line with the existing JEEE802.11 protocol, while changes the singe frame or frames ACK retransmission from JEEE802.11 protocol by recover lost data through Raptor codes which is based on FEe. All these changes aim to build a new unidirectional transmission mode, which contributes to data stream transport normally in the case of the sender exist interference source.
