Phase-shift keying (PSK) is a modulation process whereby the input signal, a binary PCM waveform, shifts
the phase of the output waveform to one of a fixed number of states. The demodulation process can be divided into three major subsections, as

Coded modulation (CM) is the combination of forward
error correction (FEC) and multilevel constellations. Coherent
optical communication systems result in a four-dimensional
(4D) signal space, which naturally leads to 4D-CM transceivers.
