DMT – Discrete Multi Tone
DMT is a digital modulation scheme based on FDM (Frequency Division Multiplexing). DMT is used across the last mile to support DSL (Digital Subscriber Line) services and is also a popular scheme for wideband digital communication systems such as WiMAX (Wireless interoperability for Microwave Access). DMT is also known as OFDM (Orthogonal Frequency Division Multiplexing).
