Hi Danilo,

pretty cool stuff! I'm looking forward to your code.

I'm curious: did you manage to create 54Mbps in realtime and send them
via the USRP2, or did you do some pre-processing? I remember trying out
how far I could push OFDM signal generation in real time, but it was way
lower than 20 MHz.

See you there -- I hope we'll find time for a chat.
