QPSK simulation with AWGN and BER using Simulink

Hi

What wrong with this block diagram and how to make monte carlo simulation and i am wondering if there any resources for this kind of modulation

Hi,

From the attached screenshot, the model seems accurate for BER calculation of QPSK modulation and demodulation. Make sure that the parameters of QPSK Modulator and Demodulator block are same. You can also try using the "Bernoulli Binary Generator" as the source of binary data.

The following example shows the implementation of a QPSK transmitter and receiver in Simulink:
