Re: [Discuss-gnuradio] How to synchronize two transmitters

[André Selva]

What I think that might be a solution is using only one computer with two USRPs. In the flowgraph, you will have two sinks. If your network card are both identical and the distance between the USRPs are not large enough to be considered, I don't see why the signals would not be syncrhonized (or, at least, very similar to each other).

I was wondering if there is a way to syncrhonize two transmitters running on two machines.

Both transmitter use OFDM. I could use a shared reference clock, but the problem is that

I don't know how exactly I can send packets SIMULTANEOUSLY from both transmitters.

I want to measure co-channel interference and study multiuser detection alogorithms.

 

Regards!
