Low‐Complexity DOA Estimation: Combining VSSLMS With FFT Spectrum Estimation
Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter presents a novel, low‐complexity framework for DOA estimation. The proposed method achieves a significant reduction in computational complexity—from O(ML) to O(M log L)—compared to conventional SSE methods. Crucially, as illustrated in the accompanying figure, the method maintains high estimation accuracy, outperforming standard SSE‐based ...

Ultra‐Wideband Coupled‐Fed Loop Antenna Pair for 5G Mobile Terminals
IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.This paper presents an ultra‐wideband (UWB) antenna pair for 5G mobile terminals. The UWB antenna pair is composed of two coupled‐fed loop antennas with a common shorted branch, which achieves a compact size. The experimental results show that the MIMO array covers 3.3–7.8 GHz with a relative bandwidth of 81.08%, and the isolation between ports is ...

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.
