USRP OFDM...

[kaiser825]

Hi. I'm newbie at USRP.

I'm  trying to verify the channel reciprocity in multi-carrier system.

so I modify conventional ofdm code a little.

but the estimated channel values(data in excel) are not same when i switch the name RIO0 and RIO1 on the front pannel. 

The data in excel is 4 by 125. 125 is # of subcarriers. So the column values have to be same but it isn't. why???

finally, last five data in row is same. I don't know why...

Please help me....
