Hi all,

I am working to compare the performance of an ofdm single transceiver and a mimo-ofdm 2x1 one. For this purpose, I would like to measure parameters at the receiver side such as snr, goodput, ber, to see the improvement that the mimo implementation should provide...So far, I've been trying it by changing how the packet is built, specifically, I am adding a field with a packet number so I can check in the receiver side how many corrects packets are received. With this method I think I can measure in a reliable way the goodput and the ber, but I still don't know how to measure the snr. I would like to know if anybody has any advice on how to do all these measurements. I am working with  GNU C++ version 4.4.1 [gcc-4_4-branch revision 150839]; Boost_103900; UHD_003.004.000-122b947, because I couldn't merge the mimo branch with the latest version of gnuradio. Thanks in advance.
