Widely linear general Kalman filter for stereophonic acoustic echo cancellation
نویسندگان
چکیده
The stereophonic acoustic echo cancellation (SAEC) problem is usually modelled as a twoinput/two-output system with real random variables. Recently, the SAEC scheme was recast as a single-input/single-output system with complex random variables, thanks to the widely linear (WL) model. In this paper, we motivate the use of a more general form of the Kalman filter with the WL model for SAEC. Simulation results indicate that this algorithm outperforms the recursive least-squares (RLS) algorithm, which is usually considered as the benchmark for SAEC. & 2013 Elsevier B.V.

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...
متن کاملA widely linear model for stereophonic acoustic echo cancellation
The stereophonic acoustic echo, due to the coupling between two loudspeakers and two microphones, can be modelled by a two-input/two-output system with real random variables. In this paper, we recast the problem as a single-input/single-output system with complex random variables, by using the widely linear (WL) model, and propose a new distortion method that fits well in this context. In order...
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...

An analysis of the system calculation complexity is also given, in addition to simulation results on recorded real-life data. Paper II presents ...
متن کاملAcoustic echo cancellation for stereophonic systems derived from pairwise panning of monophonic speech
An algorithm is introduced that performs stereophonic acoustic echo cancellation (SAEC) for systems using pairwise panning of a single monophonic source to provide the effect of spatialisation. The technique exploits the inherent high correlation between the loudspeaker signals, unlike other general SAEC techniques, which try to utilise any small uncorrelated features in the signals. The algori...
