sos!
i want to realize a 2*2 mimo simplex communication system .since rfx
daughterboards can transmit/receive 2 complex IO signals, i thought 2
usrp and 4 rfx_daughterboards is enough for me .but now i am wonfering
whether usrp can transmit/receive multiple signals simultaneously.could
somebody give a clue

Yes.
You can make a 2x2 MIMO node (meaning 2TX and 2RX) using a single USRP1
with 2 RFX-series, WBX, or XCVR2450 daughterboards. You then need
another set for the other side of the link.

thanks matt
so 2 usrps and 4 rfx dbs is enough for me ,and in usrp
multi-signals can be simultaneous.while when i send a 50K frequency
signal ,and receive it from two antennas ,through oscope i find the two
IQ signals are not synchronous£¬signal from the second antenna seems
1/4 wavelength ahead of that from the first one . do i have to modify
the rfx2400 ? and another question , when i set the mux to “32103210”
,both channel get nothing but noise ,and set to “33221100”,get the
asynchronous signals mentioned above .why? i think it should be
“32103210”.
really appreciate your help
