Thanks. I think it should be something from the 802.11 frame over the wireless link.
Since I see the time and other stuff are got from the packet, could you tell me how is the packet received from usrp (by sampling in the usrp?), what is its format? and for how we can actually do with it, is unpack the packet according to its format enough?
