GSM is a half-duplex TDMA protocol. That is, a station is only ever
transmitting or receiving, but not both at the same time.

Hello, all!
I have a question about some hardware parameters of the USRP board. What
is the antenna temperature and what is the amplifier gain after the
antenna when the board we are using is RFX2400 and the antenna is the
VERT2450 ? Thanks a lot!
The noise figure is
Hello Einar,
Knowing your modulation type can simplify your symbol and carrier
synchronization design. However, if your are not restricted with certain
modulation type and you just want to use an arbitrary modulation to get you
going then I suggest to use differential coding such as D-BPSK whic

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?
