Wideband DOA Estimation on Co-prime Array via Atomic Norm Minimization

Energies, 2020
This paper introduces a low complexity wideband direction-of-arrival (DOA) estimation algorithm on the co-prime array. To increase the number of the detectable signal sources and to prevent an unnecessary increase in complexity, the low dimensional co ...

Reduced central alpha power at rest is associated with the risk of alcohol‐induced blackout and frequency of non‐REM parasomnia episodes in adults

Physiological Reports, Volume 14, Issue 6, March 2026.
Abstract People who experience alcohol‐induced blackouts (AIBs) are at increased risk of alcohol‐related injury and even death. Blackout susceptibility is heritable and blackouts are not experienced by all who engage in hazardous drinking. Blackout is defined by amnesia, but a person in the blackout state also maintains consciousness and motor control ...

Enhanced off-grid DOA estimation by corrected power Bayesian inference using difference coarray

The Journal of Engineering, 2019
Sparse Bayesian inference for on-grid direction-of-arrival (DOA) estimation using difference coarray was investigated in the authors’ previous work to estimate more signal sources than the number of physical antenna elements. Sparse Bayesian inference is
