I am trying to implement a cognitive radio system for dynamic spectrum
access. I am trying to implement it in GNU radio. But the problem is
have only one USRP at the moment with Basic RX and TX daughterboards.
setup consists of Station A transmitting to Station B.
In order to be able to use the licensed spectrum, the transmitter must
which channels are free in the vicinity. Thus it has to do a parallel
detection of spectrum as well—receiver mode.
The Transmitter first senses the spectrum for some time say 10ms and
transmits on the free frequency for say 90 ms before sensing the
again and so on.
Thus the following questions arise:
- Can the Station B be implemented on the same USRP when the Station A
only transmitting[not sensing(recieving)]?
- What effects would this have on the Data Rates and any problem with
Is there any built in example within gnuradio with which i can test the
simultaneous transmission and reception from the BasicTX to the BasicRX
respectively on the same usrp?
