A 12-Gbps, 0.24-pJ/b/dB PAM-4 Receiver With Dead-Zone Free SS-MMSE PD for CIS Link
IEEE Access, 2023 This paper presents a PAM-4 receiver (RX) for CMOS image sensor (CIS) link. A robust baud-rate PAM-4 phase detector (PD) is proposed, which alleviates the dead zone issue encountered in the conventional sign-sign Mueller-Muller (SS-MM) PD when combined ...

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.Abstract INTRODUCTION Inhibition of pathological tau spread may slow cognitive decline in Alzheimer's disease. Here, we evaluate two tau positron emission tomography (PET) analysis methods designed for detecting tau spread. METHODS Spatial progression of tauopathy (SPOT) and tau‐naïve anatomical region of interest (tau‐naïve ROI) methods were assessed ...

NMR in Biomedicine, Volume 39, Issue 6, June 2026.We propose a novel deep learning algorithm for predicting the myelin water fraction from multiple gradient‐echo or spin‐echo pulse sequences arising in magnetic resonance relaxometry (MRR) measurements of the human brain. Our method incorporates both regularized nonlinear least squares and pure deep learning through a concatenation paradigm known as ...

Low-Complexity Banded Equalizers for OFDM Systems in Doppler Spread Channels
EURASIP Journal on Advances in Signal Processing, 2006 Recently, several approaches have been proposed for the equalization of orthogonal frequency-division multiplexing (OFDM) signals in challenging high-mobility scenarios. Among them, a minimum mean-squared error (MMSE) block linear equalizer (BLE), based

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems
International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...
