Re: Acoustic Modem For A Hobby AUV

As for acoustic, maybe you could either try to use a modem + waterproofed
speaker/mic. If that won't work you might have to implement your own
algorithm.


And I guess I'd then have to apply some form of filter to get rid of echoes
etc?

Either use the acoustic "media" as half duplex. Ie wait until sent waves have
faded out. Or use the "usual" echo cancelation techniques.
