I am implementing a QPSK modulator/demodulator by using the setup explained above.
When I use the fixed data like "Hello World" and send it without changing the message itself, the transmission is successfully completed. The transmitted and QPSK modulated data can be received and demodulated every time without any problem. But I am trying to send different data on each transmission. Unfortunately, there is problem about demodulating the data. Why the data is not demodulated when I change the data on every transmission?
