Genetic-Algorithm-Assisted Multiuser Detection in Asynchronous CDMA Communications

, 2004
—In an asynchronous direct-sequence code-division multiple-access, a specific bit of the reference user is interfered by two asynchronously arriving surrounding bits of all the other users supported by the system.

NET‐Associated Inflammatory Markers in Head and Neck Squamous Cell Carcinoma: Bioinformatic Prioritization and Exploratory Serum Assessment in Patients Undergoing Radiotherapy

Molecular Carcinogenesis, EarlyView.
ABSTRACT Neutrophil extracellular traps (NETs) and inflammatory mediators have been implicated in head and neck squamous cell carcinoma, but their relationship with systemic inflammatory status during radiotherapy remains incompletely understood. This exploratory integrative study combined a literature‐guided network‐based bioinformatic prioritization ...

Blind Multiuser Detection with Array Observations

Wireless Personal Communications, 1998
Cochannel interference is usually a major limitation to the performance of mobile wireless systems. Examples of different forms of cochannel interference include multi-access interference in CDMA systems and cochannel interference resulting from frequency reuse in TDMA systems.

Amacrine cell inputs to OFF midget ganglion cells in macaque retina

The Journal of Physiology, EarlyView.
Abstract figure legend The goal of this study was to explain the findings from physiological studies that OFF midget ganglion cells had larger receptive field centers than expected from their dendritic field diameters. First, we confirmed that OFF mRGCs (OFF MGC) receive input from diffuse bipolar cells (DB) as well as OFF midget bipolar cells (FMB ...

Adaptive near minimum error rate training for neural networks with application to multiuser detection in CDMA communication systems

, 2005
Adaptive training of neural networks is typically done using some stochastic gradient algorithm that tries to minimize the mean square error (MSE). For many applications, such as channel equalization and code-division multiple-access (CDMA) multiuser ...
