UEP Concepts in Modulation and Coding
Advances in Multimedia, 2010 First unequal error protection (UEP) proposals date back to the 1960's (Masnick and Wolf; 1967), but now with the introduction of scalable video, UEP develops to a key concept for the transport of multimedia data.

IET Power Electronics, Volume 19, Issue 1, January/December 2026.This article presents an analysis of the reconstructed modulators modulation strategy, a technique designed for energy balancing in DC‐to‐AC converters. The study evaluates the performance of this strategy, applied to a seven‐level multilevel cascade inverter. ABSTRACT This paper presents an experimental evaluation of a PWM modulation strategy based on

Joint 2‐D LFM Modulation and Mismatched Filter Design in Dual‐Function Radar‐Communication System
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper proposes a joint 2‐D LFM modulation and mismatched filtering design for military‐grade dual‐function radar‐communication systems. The novel scheme modulates data onto both the initial frequency and chirp rate of LFM pulses, boosting data rates whilst preserving the constant‐envelope property critical for high‐power transmission.

Extended GFDM Framework: OTFS and GFDM Comparison
, 2018 Orthogonal time frequency space modulation (OTFS) has been recently proposed to achieve time and frequency diversity, especially in linear time-variant (LTV) channels with large Doppler frequencies.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.We propose a multidomain joint orthogonal subspace projection algorithm based on angle‐based high‐order singular value decomposition (HOSVD). By constructing a three‐dimensional range‐Doppler‐angle tensor from multidirectional beamformed data, the method exploits the distinct spatial directivity and strong range correlation of the RFI to jointly ...

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers
