Binary, then QPSK (quad phase shift keying) 90 deg delay, then M-ary 22.5 deg delay, constant amplitude. I believe this is a maximum likelihood constant BER (bit error rate) example. If you like this, you should listen to what QPSK sounds like in music. Alan Parsons uses that in the first track on I, Robot. (use earphones, and note he is also playing notes in reverse causal sequence...very haunting to the human ear!) https://youtube/watch?v=td56XAHxLpw
