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
