Deep‐Learned Channel Estimation for MIMO‐OFDM System by Exploiting Frequency‐Space Correlation

Electronics Letters, Volume 62, Issue 1, January/December 2026.
In massive MIMO–OFDM systems, accurate channel state information acquisition is vital for reliable transmission. Traditional methods fail to fully exploit sparse channel correlation, so an attentive residual autoencoder network is proposed. It uses an autoencoder with attention and residual connections to capture frequency–space correlation, and ...

FDA‐MIMO Range and Angle Estimation Based on Hybrid Tensor Ring and CP Decomposition

Electronics Letters, Volume 62, Issue 1, January/December 2026.
The graphical abstract illustrates the RMSE performance of range and angle estimation versus SNR for different array configurations. The proposed method consistently achieves lower estimation error than existing approaches and closely matches the Cramér‐Rao bound across the entire SNR range, demonstrating its superior accuracy.

Enhancing Empirical Modal Extraction by Logarithmic Scaling and Normalization of Multi‐Area Signal Measurements

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This paper presents a hierarchical scaling and normalization method to multi‐area signal measurements that dynamically relates both the angular phase domain and its amplitude in empirical analysis of power system oscillations. The proposed approach combines logarithmic relations and the Hilbert transform to derive an effective multi‐area data scaling ...

Definition and Validation of an Exposure Measurement Method for a Typical Load of a Base Station

Bioelectromagnetics, Volume 46, Issue 8, December 2025.
ABSTRACT In the context of risk communication in mobile radio, a discussion has emerged whether exposure at common load of a base station should be presented in addition to the theoretical maximum, especially with 5G massive‐MIMO. However, a reproducible measurement method for instantaneous exposure independent of the utilization of the cell has yet to
