Write Baseband Signal to File in Simulink

Generate and write a QPSK-modulated signal to a file. Then, read the file and plot the constellation diagram of the signal.

The model cm_baseband_writer_ex1 generates a QPSK-modulated signal and writes the noisy QPSK signal to a file named bbw_example.bb.

Open a second model, cm_baseband_writer_ex2, to read the signal from the file and display the constellation diagram.
