Outlier-robust Dft-domain Adaptive Filtering for Bin-wise Stepsize Controls, and Its Application to a Generalized Sidelobe Canceller
نویسندگان
چکیده
The sensitivity against outliers due to undetected noise bursts often limits the performance of adaptive filters in applications where especially fast convergence is required, as, for example, in adaptive beamforming for audio signal acquisition or in acoustic echo cancellation. In this paper, we analyze the problem of outliers for a robust generalized sidelobe canceler (RGSC) in the discrete Fourier transform (DFT) domain and show by experimental results how outlier-robust adaptive filtering for bin-wise double-talk detectors improves the performance of the RGSC.

Application of a Double-Talk Resilient DFT-Domain Adaptive Filter for Bin-wise Stepsize Controls to Adaptive Beamforming
In adaptive filtering, undetected noise bursts often disturb the adaptation and may lead to instabilities and divergence of the adaptive filter. The sensitivity against noise bursts increases with the convergence speed of the adaptive filter and limits the performance of signal processing methods where fast convergence is required. Typical applications which are sensitive against noise bursts a...
متن کاملModification of Sidelobe Canceller System In Planar Arrays (RESEARCH NOTE)
A Side Lobe Canceller (SLC) structure is a conventional partially adaptive technique which is used in large adaptive array radars. If a desired signal has long time duration in comparison with the SLC adaptation time, signal components may be cancelled. So, this paper presents a modified SLC which eliminates desired signal cancellation problems and allows using an unconstrained adaptive algorit...
متن کاملEnhance Low-frequency Suppress
Usually the generalized sidelobe canceller (GSC) beamformer requires additional highpass pre-filtering due to insufficient suppression of low frequency directional interference, and it deteriorates the bandwidth quality of speech enhancement, especially for small size microphone array. This paper proposes a new GSC beamformer with multiple frequency dependent norm-constrained adaptive filters (...

This paper proposes a two-channel adaptive microphone array with target tracking to reduce external noise in hands-free speech communications. The proposed microphone array has two processings, one of which is beamforming and the other is target tracking. The Frequency Domain Generalized Sidelobe Canceller (FDGSC), which is the frequency domain adaptive filter derived from the time domain adapt...
متن کاملCanceling Strong Narrowband Main-beam Interference
In a generalized sidelobe canceler using normalized least mean square adaptation, interference coming in on sidelobes can be mitigated when using a small adaptation stepsize. In that case, any interference arriving from the main beam look direction will be viewed as a desirable signal, and therefore passed on. Previous studies have identified narrowband interference scenarios where interference...
