Hi Bishal - I understand the basics if what you're trying to do, but  
not the specifics.  If the TX interleaving is done in frequency (FDMA  
or OFDM) or codes (CDMA), then you should be able to do what you want  
with some clever programming.  OTOH, TDMA interleaving could be an  
issue -- depends on how you've implemented the overall system.  I can  
think of a number of ways to configure TDMA-like transmissions that  
could work in your dual USRP setup -- that said, they all require very  
clever programming.  Tell us more specifics of what you're trying to  
do, and maybe we can help more precisely (either on or off list, as  
you see fit). - MLD
