Embodiment 1
[0065] Assuming that the number of source nodes in the wireless multiple access relay network is N=4, and all source nodes and relay nodes use the same Turbo encoder, the parameters of the Turbo encoder refer to 3GPP TS 36.212, and the length of the encoding sequence is L = 1200, assuming that there are 2 source nodes S in the estimated information sequence of 4 source nodes obtained by decoding at the relay node 1 and S 3 The estimated information sequence of is correct, using the relay transmission method of the present invention, the specific implementation steps are as follows:
[0066] Step 1, the source node broadcasts the signal.
[0067] In time slot t, the source node S 1 , S 2 , S 3 , S 4 First, separate your own original data Perform Turbo encoding to obtain their respective coding sequences Then perform BPSK modulation on the respective coding sequences to obtain the respective modulation sequences Finally, the modulation sequence is broadcast to the r...

[0086] Assuming that the number of source nodes in the wireless multiple access relay network is N=4, and all source nodes and relay nodes use the same Turbo coder, the parameters of the Turbo coder refer to 3GPP TS36.212, and the length of the coded sequence is L=1200, suppose there are 3 source nodes S in the estimated information sequence of 4 source nodes obtained by decoding at the relay node 1 , S 2 and S 3 The estimated information sequence of is correct, using the relay transmission method of the present invention, the specific implementation steps are as follows:
[0087] Step 1, the source node broadcasts the signal
[0088] In time slot t, the source node S 1 , S 2 , S 3 , S 4 their own raw data Perform Turbo encoding to obtain their respective coding sequences Then perform BPSK modulation on the respective coding sequences to obtain the respective modulation sequences Finally, the modulation sequence is broadcast to the relay node R and the destinatio...
