Yes I fix this problem by reducing the sample rate and matching sample rate of Tx and Rx

I also fixed it on the transmitting-end via burst mode. I do have another problem regarding packet detection( I just see noise and no packets/waveforms). Could you help me with it My mail is ozdemir@posteo.de
I started recently with Matlab's Usrp package
Many thanks!

You need to study all the parameters because multiple factors effects your reception.
1- Gain
2- sampling rate
3- overflow
4- underflow
5- Master clock rate
6- interpolation
7-decimation etc
You need to comment out or reduce the number of visualisers in your baseband model. In addition to that you must concentrate on Tx Gain, RX Gain and the AGC gain. Additionally, different USRPs have different Tx and Rx gain ranges.
