Map output of 8-PSK onto audio

I need to modulate an 1800 Hz sinusoid with the output of an 8-PSK modulator and write that to an audio file. Then I need to read that file and recover the 8-PSK data to send to the demodulator. How could I do this? I think I have all needed Simulink libraries. Thanks.

For the modulation part:

1. Use a Sine Wave block to create the signal of desired frequency.

2. Modulate the signal using M-PSK block .

3. Save the modulated signal to audio file using To File or To Multimedia file block.

For the demodulation part:

1. Read the save audio file using From Multimedia.

2. Use the M-PSK Demodulator.

3. Bring that data to workspace , play or save it as an audio file.

You may use this example to get you started.
