qpsk costas
On first attached picture is Costas loop which can be used for QPSK carrier regeneration.
After some math, you will get that (for QPSK) e(t) is proportional to phase error (second attached picture).
My question is: can I use this same loop for 8PSK carrier regeneration? If not, how should I modify it?
Thanks in advance.
