Re: [Discuss-gnuradio] Gmsk_demod()

[José Carlos Reyes]

Hi,

I want to demodulate GSM control channels too. Particularly, I am interested in AGCH and PCH channels (GSM Down Link). Is OpenBTS what we are looking for?
I am trying to use gssm but I am having some problems with the installation.
Is better to use OpenBTS?

Thanks in advance.
Sincerely,

José Carlos

You may want to take a look at the OpenBTS code.

 $ svn co http://gnuradio.org/openbts/trunk openbts
