Triple boost switched capacitor multilevel inverter (TB‐SCMLI) with reduced components and self‐voltage balance

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
The proposed TB‐SCMLI is able to provide seven levels of output voltage by balancing the voltage of two capacitors with the given control logic. The various SCMLIs are evaluated to determine the contribution of the suggested TB‐SCMLI topology's merits and downsides.

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.

RFI Suppression Method for High‐Frequency Passive Bistatic Radar Based on Angle‐Based High‐Order Singular Value Decomposition

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

Joint Decoupling Optimization of Frequency Offsets and Array Elements for Frequency Diverse Arrays

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
Frequency diverse array (FDA) has a distance‐angle–dependent beam direction map, which has a greater application advantage than phased array. However, due to the distance‐angle coupling and periodicity of its beam direction map, it makes the parameter information of the target obtained through FDA have ambiguous phenomena. Currently, researchers mostly
