Echo Cancellation in DSL Systems
This paper gives a short review about echo cancellation techniques used in DSL systems and a short comparison between them. It should also give an overview about the basics and algorithms of echo cancellation and why it is used in Digital Subscriber Line systems.
متن کاملEcho Cancellation for Hands-Free Systems
Echo is defined as the delayed and attenuated version of the original signal produced by some device, such as a loudspeaker. As a consequence a person listens to a delayed replica of its own voice signal. This is an undesired effect that appears whenever the output signal is fed back into the system’s input and it can be quite disturbing on voice conversations. Echo arises in long distance comm...
متن کاملSubband echo cancellation in automatic speech dialog systems
Echo cancellation has been most widely studied for hands-free telephony and for cancelling line echos in telephone central o ces. The problem of echo cancelling in speech dialog systems is similar, however it has some speci c requirements. In this contribution, a subband echo cancellation structure is proposed which can be integrated in the feature extraction part of a recognizer. A NLMS gradie...
متن کاملImproved Echo cancellation in VOIP
VoIP (voice over internet protocol) is very popular communication technology of this century and has played tremendous role in communication system. It is preferred by all because it deploys many benefits it uses Internet protocol (IP) networks to deliver multimedia information such as speech over a data network. VoIP system can be configured in these connection modes respectively; PC to PC, Te...
متن کاملStereophonic acoustic echo cancellation
This paper presents a new approach for Stereophonic acoustic echo cancellation (SAEC), based on a combination of J-H network and the natural gradient algorithm. In the new approach for SAEC, Computer simulations show that echoes are significantly reduced. Disciplines Physical Sciences and Mathematics Publication Details Ge, F., Premaratne, P. & Xi, J. (2005). Stereophonic acoustic echo cancella...
