Trade of between diversity gain and multiplexing gain

[nguyenvanthien]

Hi everybody!
I hope you can answer my question( about MIMO):
probability Pe=[(2^(2R)-1)/SNR)]^2 ( R: data rate)
How can I plot trade off between diversity gain and multiplexing gain???
( My teacher suggested me: apply expressions R= r*logSNR, r: multiplexing gain
- d(r)= lim (Pe/logSNR)
( SNR > intermniable)
But it is difficult to find relationship between d and r???)
Can you help me???
Thanks!

Thanks for your answer!
But my problem is find out function d(r); then drawing d as r.
Do you have any idea?
Thanks!
