theres some threads about this, u should take a look from what i gather, the loss of packets occurring at the end of transmission is due to the transmitting USRP shutting off too early, theres a delay from sending it and it actually being in the air and then receiving it, and because it shut off before it actually waited for the last few packets to get airborne, the receiver never gets the ending ones. to rememdy this you should have ur transmitting USRP to send data in a different modulation at the beginning and end of a transmission, that way the receiver will only pick up the data in the correct modulation and the transmitter will not shut off too early.
