Quadrature amplitude modulation - Wikipedia, the free encyclopedia (1084 words)
As with all modulation schemes, QAM conveys data by changing some aspect of a base signal, the carrier wave, (usually a sinusoid) in response to a data signal.
Analogue QAM is used in NTSC and PAL television systems, where the I- and Q-signals carry the components of chroma (colour) information.
Rectangular QAM constellations are, in general, sub-optimal in the sense that they do not maximally space the constellation points for a given energy.
