Adaptive Quotient Filters [PDF]
Proceedings of the ACM on Management of DataFilters trade off accuracy for space and occasionally return false positive matches with a bounded error. Numerous systems use filters in fast memory to avoid performing expensive I/Os to slow storage. A fundamental limitation in traditional filters is that they do not change their representation upon seeing a false positive match.

Adaptive equalisation in oversampled subbands [PDF]
, 1998 The potential presence of fractional delays, non-minimum phase parts, and a colouring of the channel output can require adaptive equalizers to adapt very long filters, which can have slow convergence for LMS-type adaptive algorithms.

Combinations of Adaptive Filters
CoRR, 2016 Adaptive filters are at the core of many signal processing applications, ranging from acoustic noise supression to echo cancelation, array beamforming, channel equalization, to more recent sensor network applications in surveillance, target localization, and tracking.

Possible solution of parallel FIR filter structure [PDF]
Serbian Journal of Electrical Engineering, 2005 In this paper, a parallel form FIR adaptive filter structure with RLS (Recursive Least Squares) type adaptive algorithm is proposed. The proposed parallel form FIR structure consists of a recursive orthogonal transform stage and sparse FIR sub filters ...

Multiple model estimation with inter-residual distance feedback [PDF]
Modeling, Identification and Control, 1992 This paper presents a modification of the Multiple Model Adaptive Estimation concept. A trade-off problem between tracking the process and distinguishing the models is pointed out and an adaption of the elemental filters is proposed.

An Affine Combination of Adaptive Filters for Channels with Different Sparsity Levels
Telfor Journal, 2016 In this paper we present an affine combination strategy for two adaptive filters. One filter is designed to handle sparse impulse responses and the other one performs better if impulse response is dispersive. Filter outputs are combined using an adaptive

Effect of adaptive line enhancement filters on noise cancellation in ECG signals [PDF]
Serbian Journal of Electrical Engineering, 2021 Power line interference is the main noise source that contaminates Electrocardiogram (ECG) signals and measurements. In recent years, adaptive filters with different approaches have been investigated to eliminate power line interference in ECG ...

A Subband-Selective Broadband GSC with Cosine-Modulated Blocking Matrix [PDF]
, 2004 In this paper, a novel subband-selective generalized sidelobe canceller (GSC) for partially adaptive broadband beamforming is proposed. The columns of the blocking matrix are derived from a prototype vector by cosine-modulation, and the broadside ...

Output signal based combination of two NLMS adaptive filters – transient analysis; pp. 258–268 [PDF]
Proceedings of the Estonian Academy of Sciences, 2011 A combination of two complex normalized least mean square (NLMS) adaptive filters that adapt on the same input signal at the same time is investigated. One of the filters has a large and the other one has a small step size. The outputs of the filters are
