It is not possible because the imprint of the data lies in phase itself.

Because in PSK modulation technique the phase of the modulated is changed according to the phase of the baseband signal.

Non-coherent detection is not possible because at the receiver end the same frequency should be used as that of at the transmitter end, And coherency maintenance is must.

With respect to phase when we talk, detection is random in nature and mapping of information cannot be done correctly, so we need exact estimation and detection process.
