Acoustic Echo Cancellation Using Subband Adaptive Filtering
Adaptive ltering has been successfully used in canceling line echos in the telephone network since the 1960's [179, 443, 387]. In these cases, the adaptive lter is used to model the unknown echo path in a communications channel and then cancel the echo signals from the conversation. An adaptive lter is required because the echo path is not only unknown, but also because it is di erent for each ...
متن کاملDesign of Normalized Subband Adaptive Filter for Acoustic Echo Cancellation
In hands-free telephones and teleconferencing systems, acoustic echo cancellers are required, which are often implemented by adaptive filters. In these applications, the speech input signal of the adaptive filter is highly correlated and the impulse response of the echo path is very long. These characteristics will slow down the convergence rate of the adaptive filter if the well-known normaliz...
متن کاملSubband Adaptive Filtering with Real–Valued Subband Signals for Acoustic Echo Cancellation
Adaptive filtering in subbands have originally been proposed to overcome limitations of classic adaptive algorithms in some areas. In general, subband adaptive filters offer computational savings, as well as faster convergence over the classical Least Mean Squared (LMS) algorithm. However, improvements to current subband adaptive filters could be further enhanced by a more elegant choice of the...
متن کاملSet-membership improved normalized subband adaptive filter algorithms for acoustic echo cancellation
In order to improve the performances of the recently-presented improved normalized subband adaptive filter (INSAF) algorithm for highly noisy system, this paper proposes a set-membership version of the INSAF algorithm (SM-INSAF) by exploiting the concept of the set-membership filtering. Apart from obtaining lower steady-state error under the same convergence rate, the proposed algorithm signifi...
متن کاملAcoustic Echo Cancellation Employing Delayless Subband Adaptive Filters
The use of hands-free communication in cars, computer applications and video conferencing has created a demand for high-quality acoustic echo cancellation. In these applications the acoustic channel has typically a long impulse response in the order of 100ms. Typical lengths of adaptive FIRfilters can be 500-1500 taps. In order to reduce the complexity and also to improve the convergence rate, ...
