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 ...

OFDM with generalized index shift keying
, 2018 Recently, a family of transmission techniques known as Index Modulation (IM) have been proposed. IM schemes such as OFDM with index modulation (OFDM-IM) provide better performance than uncoded OFDM, especially at low SNR and in highly mobile environments.

Scene‐Driven Semantic Alignment for Generative Communication in Underwater Images
IET Signal Processing, Volume 2026, Issue 1, 2026.Underwater images serve as one of the most intuitive media for human perception of underwater environments. However, the limited bandwidth and susceptibility to noise in underwater acoustic (UWA) channels pose significant challenges for traditional image encoding and transmission methods, thereby hindering high‐quality image reconstruction.
