Robust Spectral and Energy Efficiency Tradeoff for RIS‐Aided Multi‐User Communication
IET Communications, Volume 20, Issue 1, January/December 2026.In this work, an RIS‐aided multi‐user network with imperfect CSI is investigated. Correspondingly, we focus on balancing SE and EE through the collaborative design of the base station (BS)'s precoding matrix and the RIS's phase shifts, which consider the transmit power budget and the channel uncertainties constraints.

Enhancing CNN Path Loss Estimation Performance using Satellite Image and Distance Feature
IET Communications, Volume 20, Issue 1, January/December 2026.Fine‐tuning a pretrained VGG‐16 accommodates efficient model retraining. Including distance feature improves path loss (PL) estimation accuracy and efficiency. The distance information is best supplied in a form in line with the empirical PL model. ABSTRACT We employ convolutional neural networks (CNNs) with distance feature and satellite image for ...
