In this paper, we develop a robust wideband adaptive beamforming algorithm for microphone array based speech recognition. We develop a quadratic constraint based …
A Krieger, E Masry - IEEE transactions on information theory, 1988 - ieeexplore.ieee.org
The convergence properties of an adaptive linear mean-square estimator that uses a modified LMS algorithm are established for generally dependent processes. Bounds on the …
WX Zheng - IEEE Transactions on circuits and systems II …, 2003 - ieeexplore.ieee.org
This transactions brief is concerned with designing adaptive filters subject to output envelope constraints in the presence of bounded noise at the input channel. The bound on …
PL Combettes, P Bondon - 1995 International Conference on …, 1995 - ieeexplore.ieee.org
We address the problem of linear mean-square estimation with arbitrary convex constraints for dependent processes. Two algorithms are proposed and their convergence is …

A method for avoiding self-oscillation in a four-wire loop in conjunction with echo cancellation is effected with the aid of an adaptive filter (15). Self-oscillation is avoided for …
Compared with single channel speech processing, multi-microphone based speech processing methods are capable of high interference suppression in noisy environments …

Envelope-constrained (EC) filtering is to design a finite impulse response filter such that the output of the filter is guaranteed to lie within a prescribed output pulse mask with respect to a …
WX Zheng - IEEE Transactions on Circuits and Systems II …, 2001 - ieeexplore.ieee.org
The problem of designing adaptive filters subject to output envelope constraints in the presence of impulsive noise at the input channel is investigated. Median smoothing is …
