Hi,
I'm using the USRP and LFRX and LFTX daughtercards for an underwater acoustics
project.
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). 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)?
I know the usrp_rx_cfile.py script saves data in complex form. For this
particular python script and an LFRX board, would the 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?
Thanks,
Dan
