receivers to maximize bit rate," IEEE Trans.
These techniques, which included carrierless amplitude and phase (CAP), quadrature amplitude modulation (QAM), and discrete multitone
(DMT), became the focus of a budding standards controversy that still dogs the xDSL industry today.
ADSL2+/VDSL2 Interface Specification (AVIS) flexible digital interface, which reduces pin-count and provides compatibility with a wide range of xDSL Discrete Multitone
LSI Logic Corporation (NYSE: LSI) today announced that it has licensed key discrete multitone
(DMT) technology from Alcatel for integration in Asymmetric Digital Subscriber Line (ADSL) system-on-a-chip (SoC) designs.
One popular scheme, known as discrete multitone
(DMT), is a variation of the quadrature amplitude modulation line code widely used in analog modems.
The technique addresses the problems that have typically limited effective bandwidth and distance capability of other high-speed transmission technologies, such as Discrete Multitone
(DMT) or Single Carrier Modulation (SCM).
Texas Instruments is pleased to provide NEC with the industry's highest-performance, lowest-power, discrete multitone
(DMT) VDSL chipset," said Jacky Chow, general manager for Texas Instruments' VDSL products.
To employ narrowband telephone wire gainfully for data requires a multilevel modulation method such as AT&T's carrierless amplitude and phase (CAP) approach or Amati's discrete multitone
