The text message is converted into a bit stream using USRP and the communication experiment using the QAM modulation method is proceeded.

I try to refer to the "QAM Modulation of an ASCII String" example in the past bulletin board, but I can not search it.

If you have the example or have any related matters, I would appreciate it if you advise me.

I want to conduct research to transmit and receive text messages using

QAM modulation and demodulation.

If you have any related data or examples, I would appreciate it if you let me know.
