Hi to all,
I resolved my problem and I want to share the solution
The problem was the amplitude in the QAM demod block input. I checked the
constellation in the transmitter directly before UHD usrp block for being
sure the the constellation points are good depending on the samples/symbol
value (8 worked good). After that i just try to adapte the amplitude signal
in reception by adding gain for to have the same signal which i had in my
QAM simulation. Like that the transmission worked good.
