Performance Analysis of Cross-band Adaptation for Subband Acoustic Echo Cancellation
نویسندگان
چکیده
In this paper, we analyze the performance of cross-band adaptation in the short-time Fourier transform (STFT) domain for the application of acoustic echo cancellation. The band-to-band lters and the cross-band lters considered in each frequency-band are all estimated by adaptive lters, which are updated by the LMS algorithm. We derive explicit expressions for the transient and steady-state mean-square error (MSE) in subbands for both correlated and white Gaussian processes. The theoretical analysis is supported by experimental results.

Scale Factor Ambiguity Correction for Subband Blind Multichannel Identification
Subband system identification has proved beneficial in applications such as acoustic echo cancellation. A problem for blind multichannel system identification in subbands is that the subband systems can only be identified correctly up to an arbitrary scale factor. This scale factor ambiguity is the same across all channels but can differ between the subbands and therefore, limits the usability ...
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 کاملA new critically sampled non-uniform subband adaptive structure
In this paper, a non-uniform subband adaptive structure with critical sampling of the subband signals is derived. With the assumption of non-overlapping between non-adjacent analysis filters, the resulting structure yields exact modeling of an arbitrary FIR system. An LMS-type adaptation algorithm, which minimizes the sum of the subband squared-errors, is obtained for updating the coefficients ...
متن کاملOn the Use of a Modiied Fast Aane Projection Algorithm in Subbands for Acoustic Echo Cancelation
The fast aane projection (FAP) has been proposed recently as a new adaptive ltering algorithm which possesses LMS like complexity but may achieve RLS like convergence. In this work, we investigate the use of FAP algorithms in subbands for acoustic echo cancela-tion (AEC). To this end, some modiications are rst made on the FAP based on the consideration of the numerical stability. The modiied FA...
