Analysis of Hybrid PAPR Reduction Methods of OFDM Signal for HPA Models in Wireless Communications
IEEE Access, 2020 Orthogonal Frequency Division Multiplexing (OFDM) suffers from a high Peak-to-Average Power Ratio (PAPR). Designing a High Power Amplifier (HPA) with high PAPR is not a wise technique as it roots the amplifier to operate in a non-linear region which is ...

A novel frequency-domain implementation of Tomlinson-Harashima precoding for SC-FDMA [PDF]
, 2009 There is considerable interest in the use of single carrier frequency division multiple access (SC-FDMA) as the uplink transmission scheme in the 3GPP Long Term Evolution standard. This interest is justified by the inherent single carrier structure of SC-

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...

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.

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.
