Energy-Efficient DSL Using Vectoring

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
A multi-user signal coordination scheme known as Vectoring will play a crucial role in next generation digital subscriber lines (DSL). Previous studies have demonstrated that vectoring increases the bitrate of DSL systems due to its ability to mitigate the interference. In this work we show how Vectoring improves the energy-efficiency of DSL over state-

Energy Efficiency or the Efficient Use of Energy Resources?

Energy Sources, 1994
Abstract This article distinguishes between energy efficiency and the economically efficient use of energy resources. Policies intended to enhance energy efficiency are unlikely to contribute to the economically efficient use of energy and are therefore likely to waste resources.

Efficient use of energy

Physics Today, 1975
Energy, it is becoming increasingly clear, is a precious commodity. Efforts are underway worldwide to seek new energy sources, to extend and conserve existing sources, and to educate consumers toward more intelligent use of the sources we have.

Energy efficiency using cooperative relaying

2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011
The rising demand for the high data rates in the future cellular systems, is directly linked with the power consumption at the transmitting nodes. Due to the various economical and environmental factors, it is becoming difficult to maintain the current rate of power consumption per unit of data, for the upcoming generations of the cellular systems ...

Efficient use of energy revisited

Physics Today, 1980
In the past several years everyone has become considerably more aware of the problems of energy supply and demand. Although extensive resources of energy are available in principle, energy that is both cheap to extract and cheap to use—such as the oil and natural gas to which we have become accustomed—is very limited.

Energy-efficient motion estimation using error-tolerance

Proceedings of the 2006 international symposium on Low power electronics and design - ISLPED '06, 2006
Presented is an energy-efficient motion estimation architecture using error-tolerance. The technique employs overscaling of the supply voltage (voltage overscaling (VOS)) to reduce power at the expense of timing errors, which are then corrected using algorithmic noise-tolerance (ANT) techniques.

Estimating Efficiency of Energy Use

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">Environmental concerns have rekindled interest in energy conservation. The central question is efficiency, and calculation of efficiency requires a numerator: the absolute minimum primary fuel necessary to produce a given product or to provide a given service.
