[0041] 1. System model
[0042] figure 1 A multi-relay cooperative system model is given, which includes a source node s, R relay nodes r i (i=1,...,R) and a destination node d. The sending power of the source node and the relay node are P s and P r . Suppose s→r i , s → d, r i The channels of →d are all flat Rayleigh fading channels, and the channel fading coefficient hsri , h sd , h rid respectively obey the mean of 0 and the variance of with complex Gaussian distribution.
[0043] 2. Implementation steps
[0044] refer to figure 2 , the present invention utilizes figure 1 The specific steps for the multi-relay space-time cooperative system to perform cooperative diversity transmission are as follows:
[0045] Step 1, the source node s generates a broadcast signal and sends a broadcast signal to the relay node r i Send d to the destination node, the specific process is as follows image 3 shown.
[0046] First, the source node s sends the source informa...
