Acoustic echo cancellation has traditionally employed basically all variants known from
deterministic adaptive filter design, such as least mean-square (LMS), recursive least …

Emerging use cases, such as keyword spotting while listening to FM radio, or participating in
a teleconference utilizing the hands-free system in a vehicle, require the utilization of multi …

This paper examines the technique of using a noise-suppressing nonlinearity in the
adaptive filter error feedback-loop of an acoustic echo canceler (AEC) based on the least …

Acoustic echo cancellation (AEC) is a well-known application of adaptive filters in
communication acoustics. To implement AEC for multichannel reproduction systems …

The paper proposes an efficient signal processing system mainly consisting of an adaptation-
based nonlinear echo cancellation (NLEC) layer and a joint perceptual subband residual …

In the process of nonlinear acoustic echo cancellation (NAEC), the eradication of echo
becomes challenging due to the nonlinear distortion introduced by the low-cost hands-free …

This paper presents a system approach to the acoustic echo cancellation (AEC) problem in
a noisy acoustic environment. We propose a method that makes use of the estimated near …

Acoustic Echo Cancellation (AEC) has ended up being a need in the present conferencing
framework keeping in mind the end goal to improve the quality of audio of hands free …

Systems and techniques for removing a Sound recording from an audio recording (eg, an
audio recording embedded in a media file) are presented. The system can include an identi …

Adaptive echo cancellation (AEC) is an essential part in hand-free full-duplex
communication to cancel the annoying echo. However, residual echo always remains even …
