XCVR2450 problem


I’ve been working on the mimo implementations on the USRP1. So far
everything works fine on RFX2400, such as packet detection,
modulation/demodulation etc. But there are some problems after I
switched to the XCVR2450 daughterboards. The packet detector keeps
reporting packets detected when there are packets transmitting on the
same daughterboard. It seems XCVR2450 is receiving the signal which is
transmitted by itself. This is not supposed to happen because XCVR2450
is half duplex even without calling set_auto_tr(true). So what’s the
problem? Is it related to the I/Q swap?
