modulation classification

hi all
i'm working on automatic modulation classification with cumulants(automatic modulation recognition)
i got stuck in a problem
i can't seperat the MPSK and MdPSK(M-ary differential psk ) modulation each other.

i can't find a robust properties for perform it.
how can i distinguish between them?
in softwar radio how can distinguish that signal is PSK or dpsk for demodulation?
totally how can blind demodulation them ?

thanks a lot.

psk dpsk classification modulation

You can get a lot from www.dsptv.com

i think you don't understand my question.
there isn't any paper or comment about this question.

There are the following Digital modulation Techniques:

1. Amplitude Shift Keying (ASK)

2. Frequency Shift Keying (FSK)

3. Phase Shift Keying (PSK)

4. Quadrature Phase Shift Keying (QPSK)

QPSK is a Combination of Amplitude Shift Keying (ASK), and Phase Shift Keying (PSK).

QPSK is one of the best Digital modulation technique, which is used for more bits to transmit the data to the destination.

Can u give some details, books or links regarding the automatic modulation recognition...

there is a lot of article aboat this topic
if you type 'digital modulation classification'
or
'digital modulation classification using cumulant'
or 'blind modulation classification'
and ...
in google.com
you can find a lot of link for download article.

sory cant help u

Added after 36 minutes:

i also need detail on the modulation techniques
that is QAM,BPSK,QPSK
