I’m using the USRP and LFRX and LFTX daughtercards for an underwater
I am confused on how the IQ (complex) and real sampling works with the
USRP (I read a couple of papers and im still lost).Â If I wish to use
real sampling and I install two LFRX and two LFTX boards can I
effectively have 4 simultaneous transmitters and 4 simultaneous
receivers (I’m aware of the 16Mhz bandwidth limitation due to USB
transfer data rate)?Â
I know the usrp_rx_cfile.py script saves data in complex form.Â For this
particular python script and an LFRX board, would theÂ RX-A input
correspond to the I portion, and RX-B input to the Q portion?
I’m still not sure what advantages there would be for using IQ sampling
for my particular application (I’m only interested in frequencies from
DC to 150 kHz). Does anyone know?
