چکیده

This paper presents the state of the art of stereophonic acoustic echo cancellation (SAEC) in terms of theoretical results and practical considerations that has to be made when implementing SAEC algorithms. The fundamental difficulty of SAEC is described and an echo canceler based on a fast recursive least squares algorithm in a subband structure is proposed. Results from real life off line experiments as well as real time experiments are shown and discussed.

روشی نو برای حذف پژواک آکوستیکی استریو با استفاده از ساختار مبتنی بر الگوریتم وفقی با ورودی برش یافته

Stereophonic acoustic echo cancellation is one of the expanding areas in the field of the speech/multimedia communication systems. In a conventional stereophonic acoustic echo canceller, working in a stereo communication system, the existence of the strong cross-correlation between the input signals to the two channels has the problem of the low convergence speed of the weights of the adaptive ...

A Spectral Dominance Decorrelation Met- Hod for Stereo Acoustic Echo Cancellation

In stereophonic acoustic echo cancellation, the two stereophonic channels are usually strongly correlated, which leads to non-unique solution of adaptive filters. Therefore, the filter misalignment gets large and the tracking capability is poor. In this paper, a novel decorrelation method based on psychoacoustic effect is proposed for stereo acoustic echo cancellation. Spectral dominance effect...

An Implementation of a Stereophonic Acoustic Echo Canceler on a General Purpose DSP

Teleconferencing systems employ acoustic echo cancelers to reduce echoes that results from the coupling between loudspeaker and microphone. To enhance the sound realism, two-channel audio is necessary. However, stereophonic acoustic echo cancellation is more difficult to solve because of the necessity to uniquely identify two acoustic paths, which becomes problematic since the two excitation si...
