Hi, I sampled a real QPSK signal of a real communication, I recorded the samples with an ADC after the Downconverter.
Now I would like to make a demodulator in matlab, both Simulink and MATLAB code are fine, my goal is just to extract the bits from the signal.
I've been trying for days both with ready-made Simulink blocks and also trying to make custom blocks, but I don't get anything. Can anyone help me or have some examples of DPSK demodulator that can be used with a real world signal (ADC samples).
Thanks in advance.
