I have a desire to use GNURadio + USRP to run a 16 QAM signal through an
amplifier, demodulate, and calculate BER or EVM or some measure of
linearity. That's the long term goal.
For the short term, I thought I would take baby steps. And I got stuck
trying to make pretty constellation plots. My

There are free options. There's the MIT course and the Lapidoth PDF book. I
suspect I might prefer a real printed book with nice graphics.
Thanks in advance,
