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 ...

MMSE decision feedback equalizer from channel estimate [PDF]

The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003
In digital radio transmission over frequency selective channels, the minimum mean-square error decision feedback equalizer (MMSE-DFE) is widely recognized as an efficient equalization scheme. In order to compute the coefficients of the feedforward and feedback filters of the MMSE-DFE, both the channel impulse response (CIR) and the variance of the ...

Tau positron emission tomography analysis methods for the quantification of tau spread in preclinical and early Alzheimer's disease

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 ...

Blind Channel Equalization with Colored Source Based on Constrained Optimization Methods

EURASIP Journal on Advances in Signal Processing, 2008
Tsatsanis and Xu have applied the constrained minimum output variance (CMOV) principle to directly blind equalize a linear channel—a technique that has proven effective with white inputs.

Input Layer Regularization and Automated Regularization Hyperparameter Tuning for Myelin Water Estimation Using Deep Learning

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 ...

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),

Chicken particle swarm optimization algorithm for MMSE equalization in MIMO systems

Franklin Open
The high density of wireless devices operating close to populated areas can result in significant Inter-Symbol Interference (ISI). Further, Co-channel interference from neighboring networks and devices can disrupt communication and might decrease signal ...
