amplify-and-forward cooperative diversity

Hello,
I am working on a cooperative diversity topic using AF relay, at which the received signal from the source is amplified and forwarded by the relay to the destination. Now, if we suppose that the source \[S\] has a single antenna, and the relay has \[N_A\] receive antennas, and we assume that the channels between \[S\] and \[R\] are i.i.d Rayleigh fading channels. We want to find the amplification factor \[G\] at \[R\], such that the transmitted power by \[R\] is \[P_R\]. How to compute \[G\]?
Regards

Dear saed, Thanks for your reply. I have confusion in basic parameters and i need your help. like how to define the Ptot i want to discuss with you about my code. i have replied in detail in my questions thread. please read it and give me a suggestion.
 

Salam,

Dear in your last reply you have written formula for relay gain and some information about power at transmitter and relay. Could you plz provide me the reference or paper for those formula. i have problem in defining the relay gain, can you help me in this problem?

looking forward for your reply!!
