We are at Aalborg University currently working on building a USRP1
based testbed for OFDMA requiring FDD/full duplex as well as TDMA
(using timestamp functionality).
In an earlier post, dated 02 Mar 2009, it was mentioned that for USRP2
some modifications had to be made for the firmware as well as host
code to support full duplex.
We are interested in inquiring whether any changes have to be made to
the USRP1 as well, and if there there are any knowledge available to
be shared regarding the combined use of FDD and TDMA i.e full duplex
as well as timestamp functionality on the USRP1.
