digital voice transmission
Hi,
I wanna build a walkie-talkie using digtal wireless modules.
The module I am using has maximum bit rate of 9600 bps.
If I sample the voice at 8000 Hz with a resolution of 8 bit then I have to send 64000 bits per second ,which is impossible using my modules.
I think I have to compress the signal,but how ?
Can anyone help me please ?I don't know any algorithms ...
