I was working on the similar problem. What about using two TX daughter

two
signals generated from two daughter boards plugged into the same
motherboard
but interleaved in some fashion so that I can study the effect of that
interleaving on the receiver side (receiver is on a different host
far from
these two simultaneously transmitting USRPs). Sorry if I am not
being clear.
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
