I have searched but did't find anything.

The 16, 32, 64, 128 versions would correspond to using different M patterns.

[Faheem Ur Rehman]

If i want to generate 16psk the i need to keep the value of M=[8 8] or M = [4 4]

[Walter Roberson]

The sum is what is important. Each entry in M corresponds to a ring. Each entry must be a multiple of 4 and the total must be a power of 2.

So for 16 you could use 4 4 4 4 or 4 4 8 or 4 12 or 8 8 or 16
