I am having difficulties understanding how to combine the two signals on
the RXA and RXB connectors on the same LFRX-daughterboard to one single
complex signal (I+Q) using the “usrp_dual_source_x” block.
The best would be to receive a float from each, and then combine the two
signals to a complex signal using the “gr_float_to_complex” block.
However it seems it is only possible to get the samples as short or
complex, so my idea is to take the real part of each of the two
“complex” signals (as they in reality are real), and combine those to
complex using the above mentioned block.
This method involves some seemingly unnecessary conversions, so I am
guessing that there is another way?
