[Discuss-gnuradio] Need help with removal of noise

[mayur_CEN]

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.
