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.

Decision Feedback Equalizers Using Radial Basis Function Networks

Journal of King Saud University: Engineering Sciences, 2000
Decision feedback equalizers (DFE)s are used extensively in practical communication systems. They are more powerful than linear equalizers especially for severe inter-symbol interference (ISI) channels with deep frequency null.

A Low-Complexity Equalizer for Video Broadcasting in Cyber-Physical Social Systems Through Handheld Mobile Devices

IEEE Access, 2020
In Digital Video Broadcasting-Handheld (DVB-H) devices for cyber-physical social systems, the Discrete Fractional Fourier Transform-Orthogonal Chirp Division Multiplexing (DFrFT-OCDM) has been suggested to enhance the performance over Orthogonal ...

Initial objects, terminal objects, zero objects, and equalizers in the category Seg of Segal topological algebras [PDF]

Proceedings of the Estonian Academy of Sciences, 2020
In this paper the initial, terminal, and zero objects in the category Seg of Segal topological algebras are described and some sufficient conditions under which the equalizers in Seg exist are found.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Design and analysis of an inductor-less cross-coupled voltage equalizer

Energy Reports, 2020
To equalize the imbalance in the state-of-charge (SoC) of lithium-ion cells, we propose a novel inductor-less cross-coupled voltage equalizer for series-connected batteries.

Pilot-Assisted OFDM for Underwater Acoustic Communication

Journal of Marine Science and Engineering, 2021
Multicarrier techniques have made it possible to wirelessly transmit data at higher rates for underwater acoustic (UWA) communication. Several multicarrier techniques have been explored in the past for wireless data transmission.

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Time-Varying FIR Equalization for MIMO Transmission over Doubly Selective Channels

EURASIP Journal on Advances in Signal Processing, 2010
We propose time-varying FIR equalization techniques for spatial multiplexing-based multiple-input multiple-output (MIMO) transmission over doubly selective channels. The doubly selective channel is approximated using the basis expansion model (BEM),
