Hello Vadim

That  sounds really cool. But is it capable of baseband processing both GSM uplink and downlink signals.

In your code available at https://github.com/axilirator/osmocom-bb which is the DSP module for SDR and what are its dependenices?

Well, I am currently working on that. I don't stick on a specific SDR
device like mentioned one.

In case of SDR, DSP part should be done on computer side, like
OsmoTRX does. And some low-level GSM L1 part is already
implemented and could be used by MS implementation too.

If you would like to cooperate me in this direction,
have a look at:


Right now I am doing some code refactoring, and further
commits will be posted at http://gerrit.osmocom.org/

With best regards,
Vadim Yanitskiy.
