Hi!
I have two radio boards on my WARP board, and I just want to ask, if it is possible to use each individual (e.g. one as transmitter, the other as interfering transmitter). Are there any constraints/hints I have to watch out?

You can use both radios simultaneously. We do this frequently with 2x2 WARPLab and the MIMO physical layers. All of the function calls in the radio controller driver (details in the API) require an argument which specifies which radios to affect. This allows one program to configure multiple radios in whatever combination your application requires.

But where I can find the code lines that have to be changed, so that I can use the radio boards sepparetly (OFDM reference design)? Or do I have to run 2 programs?

I already now that I can apply a function with #define FIRST_RADIO RADIO2_ADDR, but where I use then FIRST_RADIO again to really give it a function?

You can enable TX or RX of individual radios in warpphy.c by passing arguments to warpRadio_v1_TxEnable and warpRadio_v1_RxEnable functions.
