Text receiver is not working properly

[Maximinus]

Hello,

I have just modified the USRP transmitter and receiver examples using QAM modulation. My goal was to add sending and receiving packets in text form. Sending works correctly, but on the receiver, instead of correct text, random ASCII characters are received.

Does anyone have any idea what the problem might be and how to solve it? I am sending the appropriate VI in Appendix.
