[ns] received power into the trace file

[Daniele Piazza]

Hello,
I'm a student of engineering of Bologna. I must do some simulations with NS-2 
on the fading. I have read the paper about Ricean fading at the link 
http://www.ece.cmu.edu/wireless/, but my problems is to find the received power 
on the trace file.
So what I must make in order to show the received power?

Thanks for the attention.
