How to simulate USRP board?

My name is Ketlin and I’m from Brazil. I am researching the technology
of cognitive
radio, I’m not USRP board, I wonder if there is any way to simulate the
plate without the USRP hardware?

Gnuradio works fine without a USRP. You only need a USRP if you are
planning on transmitting or receiving real signals.

–n

More specifically, on the receive side, you can use a file source
for samples that have either been captured by someone else, or
generated by something like Matlab. On the transmit side, you can
simply sink any generated samples into a spectrum display.

Since you will not have any hardware in the simulation to provide
a real-time “pacing”, you will need to add a throttle block
(only one!) to each flowgraph to keep it from consuming all
cpu cycles.
