Hi all,
I would like use a USRP as a GSM base station. Is it possible to make it Tx and Rx at the same time? How?
In "A Survey on Spectrum Management in Cognitive Radio Networks" (the link), (page 44) it mentioned CR users should stop transmitting while sensing. I am confused. Does it mean that even though the CR user has two transceivers, the CR user still cannot sensing and transmitting at the same time?
Thank you,
Jane
