RE: Need Help
Many types are there like:
Amplitude-shift keying (ASK), Frequency-shift keying (FSK), Phase-shift keying (PSK).

In 8PSK which means Phase shift keying, there are 8 different phase changes, each phase change represents the transmission of 3 bits.

16 PSK - 16 Point Phase Shift Keying. 16APSK uses two amplitude levels, A1 and A2, plus 16 different phase positions with an offset of θ. 16APSK uses a double-ring PSK format. This is called 4-12 16APSK with four symbols in the center ring (A2) and 12 in the outer ring (A1).
