What is 8 phase shift keying?

Answer 1

8 phase shift keying is a complex form of digital modulation by altering a sine wave and a cosine wave: shifting their phase.

The best explanations I have found so far can be found at

http://en.wikipedia.org/wiki/Phase-shift_keying

and

http://www.sss-mag.com/pdf/1modulation.pdf

But they all explain the more simpler forms of phase shift keying:

Binary Phase Shift Keying (BPSK) and

Quadrature Phase Shift Keying (QPSK)

and they don't say much about 8PSK unfortunately.

However this might still give you an idea.

Good luck, I will keep searching myself.
