Hello,
I am working on an experiment to send a text file over the fm
channel.While
recording the Fm channel ,white gaussian noise(the constant fm channel
noise,i hope that what u call it) is also recorded at the beginning and
end
of the file.I want to remove this noise before I send it to the deocder
program.I am saving the received Fm file in .wav format.Can anyone help
me
out?I am not very well versed with communication concepts.Hope someone
will
throw some light on the white Gaussian noise concept.I would like to
know
about it?why is it produced in an FM channel and not in gsm of Wifi?
Thanks a lot for all your replys till now.
