[Discuss-gnuradio] 802.11 Transmit with Barker spreading on USRP1?

[Phillip Walsh]

Hi all,

I  am working on a project where I am trying to have the USRP1 transmit and 
receive 802.11 management and control frames to/from commercial 802.11b 
hardware.  I have the receive functionality working fine using BBN 802.11and 
the SPAN receiver on GNU Radio 3.1.1.  I see there is a lot of work being done 
updating BBN to work on GNU Radio 3.2 for the USRP2. My question is has anyone 
been able to successfully transmit DBPSK DSSS (Barker chipping and all) using 
the USRP1?  

Due to the bandwidth limitations imposed by USB2.0, is the best plan of attack 
to move the spreading down to the FPGA similar to what U. of U SPAN did with 
the receiver?  

Also, I have the current trunk of GNU Radio 3.2 on another boot of Ubuntu so I 
am not stuck on working with the antiquated version if someone has BBN working 
on it with the USRP1.

Regards,

Phil Walsh
