Hi,

Can someone please confirm the following for me ..
This realtes to PSK or phase shift keying.

Is it right that 8PSK uses eight different phase shifts each representing one of the eight patterns of three bits ... ??

Does it ehn follow that 256PSK uses 256 different phase shifts each representing one of the 256 patterns of eight bits ???

I base this assumption on ..

2 4 8 16 32 64 128 256

1 2 3 4 5 6 7 8 bits

Can you please confirm I am right ?

Thank you for your help

Oddie
