An online algorithm for echo cancellation, dereverberation and noise reduction based on a Kalman-EM Method

EURASIP Journal on Audio, Speech, and Music Processing, 2021
Many modern smart devices are equipped with a microphone array and a loudspeaker (or are able to connect to one). Acoustic echo cancellation algorithms, specifically their multi-microphone variants, are essential components in such devices.

Segmentation‐enhanced gamma spectrum denoising based on deep learning

IET Communications, Volume 18, Issue 1, Page 63-80, January 2024.
This paper proposes a segmentation‐enhanced convolutional neural network‐stacked denoising autoencoder (CNN‐SDAE) method based on convolutional feature extraction network and stacked denoising autoencoder to achieve gamma spectrum denoising, which adopts the idea of data segmentation to enhance the learning ability of the neural network.

Inverse Filtering and Principal Component Analysis Techniques for Speech Dereverberation

Advances in Electrical and Electronic Engineering, 2016
In this work, we present a single channel approach for early and late reverberation suppression. This approach can be decomposed into two stages. The first stage employs the inverse filter to augment the signal-to-reverberant energy ratio.

Improving the conditioning of the optimization criterion in acoustic multi-channel equalization using shorter reshaping filters

EURASIP Journal on Advances in Signal Processing, 2018
In acoustic multi-channel equalization techniques, such as complete multi-channel equalization based on the multiple-input/output inverse theorem (MINT), relaxed multi-channel least-squares (RMCLS), and partial multi-channel equalization based on MINT ...
