Hi list,
I want to introduce some artificial degradation to a speech signal in order to simulate speech degradation in a GSM network transmission.
The addition of a background noise seems to be simple but I don't know which type or noise distribution I have to use.
I want also introduce frequency degradation and I have no idea about the way this must be done.
Can anyone advice me or send me some documentations about this topic?
Best Regards.
F.B.A.
