* Implement QPSK TX - RX with USRP hardwareNao Pross2021-10-285-26/+3361
| | | | | | | | | | And fix some small issues in QPSK simulation. The signal flow graph was tested with a coaxial cable, as well as with an 2.4 GHz antenna. The constellation diagram looked OK, but the sent data (bytes of lena512color.tiff) were neither decoded nor tested. That is because we need to synchronize data frames with a header thing or something like that (which is still not implemented yet).

| | | | | | | | | | | | | | | | | | Actually because of how gnuradio works it would be a mess to have a virtualenv. It is easier to just run $ pip3 install dearpygui instead. And the other deps (numpy) are installed anyways.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the work of commit 20e54b3cf198f17e05a3c7e8716138717447aa32 Important: - The diagram has been updated to include a CMA equalizer and a costas loop (for phase correction and small frequency correction). TODO: - Decode the signal - Create USRP hardware sinks (RX side, for later) It would be very nice if we manage to find a 'switch' block that allows to have in a single flow diagram both the simulated and "real" signals. NOTE: recall that the USRP gives directly a baseband signal, which means that everything between the channel the costas loop (both included) will not be used when the hardware is connected. Only the (not yet) implemented decoder (and eventually some more filters if needed) will be used. Other notes: - The layout has been updated to use QT Tab widgets (defined on the top left corner). GUI elements can be put into tabs by giving a string '<tab name>@<tab nr>: <grid options>' as GUI hint. - To make the diagram nicer, all GUI sinks (eg. constellations plots of time / freq. plots) are vertically aligned. Constellation above, and time and freq. sinks below. Variables ought to be placed near their respective block, unless they are global, in which case they should go on the top left.
