Looking for MIMO measurement-related information

Hi,

I have made channel measurements for MIMO channel. Basically i am transmitting with two antenna and receiving with two antennas. I need to normalize the channel matrix in order to remove the inbuilt SNR so that I can calculate the capacity at any SNR. Please let me know if anyone has any references, or anyone out there has made some measurements already and knows what to do. It would be of great help to me.

Thanks and regards
Abhishek
