Re: [Discuss-gnuradio] GNU Radio Conference 2011

Scott,

I thought the frequency offset should be taken care of by the receiver synchronization? The 802.11 NIC don't have external reference but they can still sync to the AP.

Thank you,

Johnny

If you are having frequency offset problems, you need to synchronize the USRPs with an external reference, i.e. a GPS receiver.

Martin,

Thanks for the suggestion! I think it's a good idea. I remember having a lot of problems with the OFDM receiver. The frequency offset between the 2 oscillators screwed things up. Looking around, I don't think this issue has been resolved. Correct me if I'm wrong.

Thank you,
Johnny

   Hi everyone,

   I actually think doing something *with* GNU Radio is the more
   interesting part, at least at the beginning. How about you start
   writing
   a receiver for your favourite comms standard?

   That way, you can start with a fairly simple environment, use a lot of
   code templates and concentrate on what you already know.

   Once you start doing that, you will inevitably end up with something
   that annoys you, something you feel is inefficient or whatever. Then
   you've got something to discuss about at the conference :)
