* Implement QPSK TX - RX with USRP hardwareNao Pross2021-10-283-0/+3336
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).
