[0032] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] The present invention provides a kind of LDPC decoding method based on relay cooperation, comprising the following steps:
[0034] Step A): The source node broadcasts information to the destination node and the relay node;
[0035] Step B): The destination node decodes and outputs the received source information and checks it, sets the retransmission request information F according to the verification result, and forwards the retransmission request information F to the relay node, if the decoding is correct , return to step A), otherwise go to step C);
[0036] Step C): The relay node performs adaptive demodulation according to the received retransmission request information, and forwards it back to the aforementioned destination node;
[0037] Step D): The destination node performs correlation estimation bas...
