whitepaper The gains in rate/reach performance are most significant for deployment scenarios where crosstalk is the dominant noise source and where a substantial reduction in crosstalk can be achieved. Crosstalk is one of the main limitations of DSL...
[11 Oct 2005]
whitepaper It is shown that when the noise at the input is highly impulsive, significant reduction in the signal to noise ratio can be achieved. Although multicarrier modulation techniques are inherently more resistant to impulse noise than single carrier...

whitepaper This paper explores the issue of coupling noise reduction, and proposes performance metrics that can be used by the designer to determine which of the alternative methods is best suited for a specific interconnect configuration.
[29 Mar 2005]
whitepaper The interface addresses the noise reduction challenges by utilizing a pseudo-differential reference with noise immunity approaching that of a fully differential reference. Furthermore, noise generation is reduced by on-chip termination, and low...

Comment In a voice over IP environment, only conversation or other noise is transmitted across the network. Instead the data network can handle both voice and data with a significant reduction in the required network capacity and therefore cost.
[21 May 2004]
whitepaper For noisy speech at a low 10 dB input SNR, for example, the proposed algorithm can achieve on average about 13 dB noise-to-mask ratio (NMR) reduction, or about 6 dB SNR improvement. We propose a new adaptive speech noise removal algorithm based on...
