Turbo Equalization Based on a Combined VMP-BP Algorithm for Nonlinear Satellite Channels

IEEE Access, 2018
Close to saturation operation of high power amplifier (HPA) leads to strong nonlinear and dispersive characteristic of satellite channels. At the receiver, the observation signals are distorted by not only the linear inter-symbol interference (ISI) but ...

Trust at Your Own Peril: A Mixed Methods Exploration of the Ability of Large Language Models to Generate Expert‐Like Systems Engineering Artifacts and a Characterization of Failure Modes

Systems Engineering, Volume 28, Issue 5, Page 583-604, September 2025.
ABSTRACT Multi‐purpose large language models (LLMs), a subset of generative artificial intelligence (AI), have recently made significant progress. While expectations for LLMs to assist systems engineering (SE) tasks are paramount; the interdisciplinary and complex nature of systems, along with the need to synthesize deep‐domain knowledge and ...

Optimization of LDPC Codes over the Underwater Acoustic Channel

International Journal of Distributed Sensor Networks, 2016
To combat severe intersymbol interference incurred by multipath propagation of sound waves in the underwater acoustic environment, we introduce an iterative equalization and decoding scheme by iteratively exchanging soft information between a low-density

Effects of AI‐generated adaptive feedback on statistical skills and interest in statistics: A field experiment in higher education

British Journal of Educational Technology, Volume 56, Issue 5, Page 1735-1757, September 2025.
Abstract This study explores whether AI‐generated adaptive feedback or static feedback is favourable for student interest and performance outcomes in learning statistics in a digital learning environment. Previous studies have favoured adaptive feedback over static feedback for skill acquisition, however, without investigating the outcome of students ...

Interference Coordination for E-MBMS Transmissions in LTE-Advanced

International Journal of Digital Multimedia Broadcasting, 2010
Interference coordination methods for Evolved-Multimedia Broadcast/Multicast Service (E-MBMS) in Long-Term Evolution Advanced (LTE-A) are presented. In addition, we consider signal space diversity based on Rotation Matrices (RM) known to provide good ...

Sub-Nyquist Field Trial Using Time Frequency Packed DP-QPSK Super-Channel Within Fixed ITU-T Grid

, 2015
Sub-Nyquist time frequency packing technique was demonstrated for the first time in a super channel field trial transmission over long-haul distances. The technique allows a limited spectral occupancy even with low order modulation formats.
