Stereophonic 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.

متن کاملSubband Affine Projection Algorithm for Acoustic Echo Cancellation System
We present a new subband affine projection (SAP) algorithm for the adaptive acoustic echo cancellation with long echo path delay. Generally, the acoustic echo canceller suffers from the long echo path and large computational complexity. To solve this problem, the proposed algorithm combines merits of the affine projection (AP) algorithm and the subband filtering. Convergence speed of the propos...
متن کاملAcoustic Echo Cancellation Postfilter Design Issues For Speech Recognition System
In this paper a generalized postfilter algorithm design issues are presented. This postfilter is used to jointly suppress late reverberation, residual echo, and background noise. When residual echo and noise are suppressed, the best result obtains by suppressing both interferences together after the Acoustic echo cancellation (AEC). The main advantage of this approach is that the residual echo ...
متن کاملMultichannel Teleconferencing System with Multi Spatial Region Acoustic Echo Cancellation
In this paper a novel configuration for multichannel teleconferencing with multi spatial region acoustic echo cancellation is developed. In the proposed configuration, the transmission and receiving rooms are divided into equivalent number of spatial regions and adaptive filters are attached to each spatial region for the purpose of echo cancellation. This multi spatial region acoustic echo can...
متن کاملSystem identification using orthogonal functions and application to acoustic echo cancellation
In this paper, a new Iaguerre domain adaptive filter algorithm, which will be refered to as the Laguerre domain adaptive filter II (LDAF It) has been proposed. The performance of the adaptive filtering algorithms simulated for acoustic echo cancellation application. The performances of the algorithm are specified using various quantities. All the results of the work, for different performance q...
