Signal Processing Letters, IEEE, 2002
A residual echo cancellation scheme based on the autoregressive (AR) analysis is proposed for hands-free telephony. Residual echo is whitened by the inverse filter using the estimated AR coefficients. Removing the speech characteristics of the residual echo signal, the noise reduction system successfully reduces the power of residual echo as well as that of ambient noise. In a car cabin, ...
Digital Signal Processing (DSP), 2011 17th International Conference on, 2011
The aim of this paper is the presentation of a comparative analysis of Hammerstein and Wiener systems used for the problem of compensation of the nonlinear distortion due to non-ideality of amplifiers and loudspeakers in acoustic echo cancellation. The proposed solutions consist in a cascade of a flexible nonlinear function, whose shape can be modified during the learning process, and ...
Acoustics, Speech, and Signal Processing, 1995. ICASSP-95., 1995 International Conference on, 1995
The effect that cross-correlation between stereo signals has on a stereo echo canceller is studied and a new stereo projection echo canceller is proposed that can identify the true echo path impulse responses. This echo canceller accelerates filter coefficient error convergence by adding the variations in the cross-correlation to stereo signals or by utilizing the fact that the cross-correlation between ...
Signal Processing (ICSP), 2010 IEEE 10th International Conference on, 2010
This paper presents a new echo canceller using double talk detector based on the accumulated number of selection of the scale factor. Computational complexity of the proposed method is very simple because scale factor is calculated by the double-talk robust adaptive algorithm. Computer simulation using real speech signals shows that the echo canceller using the proposed double talk detector outperformed ...
Sarnoff Symposium, 2007 IEEE, 2007
In this paper segment variable-step-size proportionate normalized least mean square (SVS-PNLMS) algorithm is proposed for acoustic echo cancellation (AEC) application which is introduced as an important issue in services like video conferencing. The analysis reveals that it performs a faster convergence rate compared to that of the recently introduced SPNLMS (segment proportionate normalized least mean square), PNLMS (proportionate normalized least ...

We derive a new frequency-domain adaptive algorithm by using a frequency- domain recursive least squares criterion, minimizing an error signal in the frequency-domain. We then derive an exact adaptive algorithm from the so- called normal equation. It is shown that the obtained algorithm is complex to implement, and to reduce the complexity we need to remove a constraint resulting in ...

A 60-MHz 64-tap adaptive finite-impulse-response (FIR) filter chip was fabricated in 1.2-μm CMOS. It can implement either an echo canceler or a decision feedback equalizer for 2B1Q high bit rate digital subscriber line (HDSL) transceivers. The 4.3×4.3 mm2, 30000 transistor chip is a completely self-contained adaptive filter which incorporates the least mean square (LMS) algorithm for coefficient updating. The device ...

Echo cancelers which cover longer impulse responses (⩾64 ms) are desirable. Long responses create a need for more rapidly converging algorithms in order to meet the specifications for network echo cancelers devised by the ITU (International Telecommunication Union). In general, faster convergence implies a higher sensitivity to near-end disturbances, especially "double- talk." Previously, a fast converging algorithm called the proportionate ...

This paper presents a very high-speed digital subscriber line (VDSL) solution called synchronized discrete multi-tone (SDMT), which is a flexible, low- complexity time-division duplexed implementation of DMT that provides key desirable VDSL features. The measured performance results quantify the achievable ranges and data rates of a currently-available SDMT VDSL system.
