Modulation and Demodulation FSK/BPSK

Hi,

Need help to create a modulate/demodulate file.

1. I have "DATA_X" that I need to modulate then demodulate after to simulate data transmitted.
2. I then have to add random noise to this modulate to see how much data transmitted is correct or incorrect after demodulated.

I just need some examples that I can utilize with the matlab communications toolbox since I have not used this add-on before.

Thank you!
