International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 39, Issue 3, May/June 2026.ABSTRACT Behavioral models for Power Amplifier (PAs), particularly those based on Neural Networks (NNs), often suffer from high computational complexity when handling wideband signals. In this paper, we present a novel behavior model for wideband GaN PAs based on a Two‐Sided Temporal Convolutional Neural Network (TST‐CNN).

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Electronics Letters, Volume 62, Issue 1, January/December 2026.We propose a Doppler‐tolerant DFT‐spread orthogonal time‐coded OFDM (DSS‐OTC‐OFDM) waveform for MIMO radar that maintains orthogonality under Doppler shifts while enabling flexible code design. An optimisation framework is developed to minimise peak sidelobe level (PSL) and suppress cross‐correlation after matched filtering across a range of Doppler ...

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]
, 2009 At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

Research on Peak‐to‐Average Power Ratio Control Method for Switched Reluctance Pulse Generator
IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.Addressing the different requirements for peak output power when SRPG supplies power to pulse loads and DC loads, the peak‐to‐average power ratio (PAPR) is taken as the generation performance optimisation parameter. By investigating the power characteristics of the SRPG, the influence of control parameters on the PAPR is studied.

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.This document presents a revised mathematical framework for underwater 6G networks addressing common mistakes in research that result in overly optimistic outcomes. By employing established physical models and stringent technical limitations, we create a self‐validated benchmark of 776 Mbps over a distance of 44.8 m in clear ocean water with ...

Multispectrally Constrained Waveform Design for MIMO Radar Direction Finding
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper focuses on the design of transmit waveforms for multiple‐input‐multiple‐output (MIMO) radar systems in a spectrally crowded environment. The purpose is to improve the angle estimation performance of MIMO radar by minimising the asymptotic estimation bound of multiple signal classification (MUSIC) algorithm.

Spectrally Compatible Deceptive Jamming Waveform Design for Synthetic Aperture Radar Countermeasures
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper focuses on the design of synthetic aperture radar (SAR) deceptive jamming waveforms with spectrum‐compatible capability. By using the synthesised jamming waveform, successful deception against the hostile SAR system is demonstrated by generating false targets with high fidelity in both range and azimuth.
