carrierless amplitude/phase (CAP)

Definition

carrierless amplitude/phase (CAP)

Carrierless amplitude/phase (CAP) modulation was the original approach for modulation of a Digital Subscriber Line (DSL) signal. Discrete multitone (DMT) is now the preferred modulation alternative over CAP.

CAP is closely related to quadrature amplitude modulation (QAM).
