The Four‐Square Step Test With and Without Dual Tasks Among Older Adults With and Without a Fall History: A Retrospective Cohort Study

Health Science Reports, Volume 9, Issue 2, February 2026.
ABSTRACT Background and Aim As the global population of adults aged 65 and older increases, so does the prevalence of falls, which are the second leading cause of unintentional injury deaths worldwide, according to the World Health Organization. The Four‐Square Step Test (FSST) is a widely used tool for assessing dynamic balance and mobility.

Turbo-per-Tone Equalization for ADSL Systems

EURASIP Journal on Advances in Signal Processing, 2005
We study the equalization procedure in discrete multitone (DMT)-based systems, in particular, in DMT-based ADSL systems. Traditionally, equalization is performed in the time domain by means of a channel shortening filter.

Performance analysis of WPM‐based transmission with equalization‐aware bit loading

ETRI Journal, 2018
Wavelet packet modulation (WPM) is a multicarrier modulation (MCM) technique that has emerged as a potential alternative to the widely used orthogonal frequency‐division multiplexing (OFDM) method.

Improving the convergence property of DFE using the deterministic blind channel estimation

Tongxin xuebao, 2005
A blind decision feedback equalizer （DFE） algorithm was proposed. The subspace method which was based on the second-order statistics （SOS） was employed to give the parametric estimation of channels unsupervised.
