[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation examples.
[0033] Fountain code uses a linear encoding and decoding method, which allows the sending end to continuously generate encoding symbols, and does not stop encoding and sending until it receives feedback from the user that it has been correctly received. It is a channel encoding that increases transmission reliability. The sender does not need to know the channel state information of the legal receiver, but it can still ensure reliable data transmission. When the sending end of wireless transmission uses fountain code encoding, it will stop encoding and sending until it receives feedback from the legal receiving end that it has received correctly.
[0034] The core idea of the present invention is that in the process of wireless data transmission, the sending end uses the fountain code encoding method to encode k informat...
