Coherent Vs Non Coherent Modulation (Introduction)
On the Basis of presence of Phase-Recovery circuit, we can classify digital modulation techniques into coherent or non coherent techniques.Watch the Complete Video Here-
The job of the phase recovery circuit is to keep the oscillators supplying locally generated carrier wave at the receiver; in synchronizm to the oscillator supplying carrier wave at the transmitting end.
Actually, We use carrier waves at the transmitting and receiving ends both and for coherent detection these two Carriers should be in synchronism. Here synchronism means, synchronization in both frequency and phase.
Coherent Digital Modulation Technique
This technique employs coherent detection, the local carrier wave which is generated at the receiver is phase locked with the carrier at the transmitter.Hence both the oscillators (carrier waves) are synchronized in both frequency and phase.
In coherent digital modulation technique, The error probability decreases but the system becomes complex.

Non Coherent Digital Modulation Technique
In non coherent digital modulation technique, there is no need for the two carriers (at transmitter and receiver) to be phase locked.Although in non-coherent technique the system becomes simple but the error probability increases which is in contrast to the coherent detection method.
