= Phase offset modulation
{wiki=Phase_offset_modulation}
Phase Offset Modulation (POM) is a technique used in signal processing and communications where information is conveyed by varying the phase of a carrier wave. It is a type of phase modulation (PM) in which discrete phase states are used to represent different signals or symbols. In POM, the key idea is to impart data onto a carrier signal by introducing specific phase offsets. The carrier signal's phase is altered by predetermined values, which correspond to specific data bits or symbols.
