WebNov 27, 2024 · In coherent detection, the receiver derives its demodulation frequency and phase references using a carrier synchronization loop. Such synchronization circuits may introduce phase ambiguity in the detected phase, which could lead to erroneous decisions in the demodulated bits.

Webmances of coherent M-PSK and non-coherent differential M-PSK (M-DPSK). They assumed that the channel phase was unknown to the receiver, but was constant over multiple symbol intervals. The detection was made based on an observation interval consisting of more than two received symbols.
