8PSK demodulator

Dear Sir:

What is the diadvantage if we only extract phase information
from a 8PSK signal to demodulate it?

Anyone has papers?

Thanks in advance.

The attached pdf shows a compartive study of various modulation scheme. From the graphs you can infer the the davnatages as well as disadvantages of 8PSK in comparison to other available schemes.

did not mention effect of receiver non-linearity.

Thanks,
