[Discuss-gnuradio] Is it possible to make a USRP Tx and Rx at the same time?

[Jane Chen]

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?

http://wireless.cs.uh.edu/presentation/2008/oct24_survey_spectrum_management_cogn_radio.pdf

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
