I need to perform underwater communications in a range up to 100m. I will use transceivers in order to create the sound waves. I will use FSK to modulate the data, lets say 100khz for value '0' and 110khz for value '1'. The data would be coded with RTTY/Baodot scheme.
I am a newbie with Arduino's technology and I would like to know if it is capable to perform all these operations:
1- Create a FSK modulation. 2- Receive FSK and demodulate it.
The RTTY seems to be fully implementated with some already done libraries.
I have seen some libraries like SoftModem that I could use but I am not completely sure.
What do you thing about it?
