A soft-partitioned frequency-domain adaptive filter for acoustic echo cancellation
نویسندگان
چکیده
We present a sop-partitioned frequency-domain adaptive filter (SPFDAF) and compare it in the context of other LMS type acoustic echo cancelers. The SPFDAF uses a non-rectangular window to partition the model taps (impulse response) of an echo canceler. Our soji window can be approximated very efficiently in the DF? domain and still attenuates aliasing components of the DFT by 40 dB. This technique results in a very low computational complexity and maintains an excellent signal quality.

Partitioned residual echo power estimation for frequency-domain acoustic echo cancellation and postfiltering
Residual echo arises in hands–free telephony equipment due to insufficient echo canceler convergence, but can be suppressed using a postfilter. The residual echo power spectral density is the most crucial control parameter for both frequency–domain acoustic echo cancellation and combined residual echo and noise postfiltering. In this contribution we present and compare residual echo power spect...

متن کاملPerformance Analysis of Acoustic Echo Cancellation Techniques
Mainly, the adaptive filters are implemented in time domain which works efficiently in most of the applications. But in many applications the impulse response becomes too large, which increases the complexity of the adaptive filter beyond a level where it can no longer be implemented efficiently in time domain. An example of where this can happen would be acoustic echo cancellation (AEC) applic...
متن کاملA Multi-filter Approach to Acoustic Echo Cancellation for Teleconferencing
We have designed and tested an acoustic echo cancellation system for speech teleconferencing. Our algorithm is based on a least-mean-square (LMS) frequency domain adaptive filter (FDAF) and uses a novel filter-update technique using many (at least 3) simultaneously running filters. We find the new multi-filter to converge faster than similar LMS FDAF’s for echo cancellation, and find it to be e...
متن کاملA Frequency Domain Nonlinearity for Stereo Echo Cancellation
This letter proposes a novel nonlinear distortion for the unique identification of receiving room impulses in stereo acoustic echo cancellation when applying the frequency-domain adaptive filtering technique. This nonlinear distortion is effective in reducing the coherence between the two incoming audio channels and its influence on audio quality is inaudible. key words: acoustic echo cancellat...
