A frequency domain stereophonic acoustic echo canceler exploiting the coherence between the channels
نویسندگان
چکیده
Stereophonic acoustic echo cancellation (AEC) is typically intended for use in high quality teleconferencing systems and multiparticipant desktop conferencing that implement sound transmission through two channels. Because of the high correlation between the two channel signals, rapidly converging adaptive filter algorithms (such as the two-channel fast recursive least-squares FRLS) are required. In this paper, we propose a new and efficient frequency domain adaptive algorithm that achieves this goal. c ©1999 Acoustical Society of America PACS numbers: 43.60.Gk, 43.60.Lq

Stereophonic Acoustic Echo Cancellation: Theory and Implementation
The thesis treats theory and implementation aspects for stereophonic acoustic echo cancellation. In Paper I a complete implementation of a stereophonic acoustic echo canceler based on the two-channel fast recursive least-squares algorithm is presented. An analysis of the system calculation complexity is also given, in addition to simulation results on recorded real-life data. Paper II presents ...
متن کاملStudies of a Wideband Stereophonic Acoustic Echo Canceler
In this paper a wideband stereophonic acoustic echo canceler is presented. The fundamental difficulty of stereophonic acoustic echo cancellation (SAEC) is described and an echo canceler based on a fast recursive least squares algorithm in a subband structure is proposed. This structure have been used in a real-time implementation, on which experiments have been performed. In the paper, simulati...
متن کاملA Hybrid Frls/nlms Stereo Acoustic Echo Canceler
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...
متن کاملNew insights into the stereophonic acoustic echo cancellation problem and an adaptive nonlinearity solution
In this paper, we expand the knowledge regarding the problems of two-channel (or stereophonic) echo cancellation. The major difference between two-channel and the single-channel echo cancellation is the problem of nonunique solutions in the twochannel case. In previous work, this nonuniqueness problem has been linked to the coherence between the two incoming audio channels. One proven solution ...
