Low-Complexity Detection/Equalization in Large-Dimension MIMO-ISI Channels Using Graphical Models

, 2011
In this paper, we deal with low-complexity near-optimal detection/equalization in large-dimension multiple-input multiple-output inter-symbol interference (MIMO-ISI) channels using message passing on graphical models.

Engagement and task satisfaction during cognitive stimulation tasks facilitated by a social robot versus a human research assistant

Alzheimer's &Dementia, Volume 21, Issue S4, December 2025.
Abstract Background Social robots have emerged as cutting‐edge technology in the care of older adults, with potential applications in cognitive stimulation. However, the interactive capabilities of these robots remain limited. This study aimed to compare engagement and satisfaction among long‐term care home (LTCH) residents during cognitive activities ...

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.
