FFT phase spectrum to suppress noise?

Question

All that I heard so far about phase spectrum - that it is very hard to process. Are there any methods to do that, and is it possible to extract information about the noise from phase spectrum?

Answer 1

you can look at

the short answer is that for noise, phase is random. There shouldn't be any structure to exploit, while for signal, there often is.
