Reliable UAV Video Streaming Over 5.9 GHz and mmWave Bands: Comparative Analysis With Fountain Codes in Urban and Industrial Environments

IET Communications, Volume 20, Issue 1, January/December 2026.
This article presents an adaptive unmanned aerial vehicle video streaming framework in which captured video is encoded at multiple quality levels and protected using Luby transform (LT) coding before transmission over a wireless channel to a base station. At the receiver, LT decoding and latency monitoring are used to assess delivery performance, while

A Geometry‐Based Stochastic Channel Model and Beam Domain Transformation for Satellite‐to‐UAV Communications

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a 3D geometry‐based stochastic model and its beam‐domain transformation for satellite‐to‐unmanned aerial vehicle (UAV) communication channels across S to Q bands. The models capture key physical effects, including spatial consistency and atmospheric influence, while enabling efficient simulation of channel statistics under varying ...

SKE2SG: A Secure Key Establishment Scheme for Smart Grid Cyber‐Physical Systems Based on Elliptic Curve Cryptography

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

Deep Learning-Assisted Multicast Subgrouping in Massive MIMO

IEEE Open Journal of the Communications Society
Efficient content delivery in massive multiple-input multiple-output (mMIMO) multicasting is fundamentally limited by pilot overhead and the need to serve heterogeneous users with a common transmission rate.

Adaptive Bitrate Streaming With Video Quality Enhancement

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We bring the new factor, DVQE sensitivity, into the bitrate selection for the QoE improvement of adaptive video streaming. We develop DSABR, which selects chunk bitrate with high DVQE sensitivity to improve video quality as well as reduce bandwidth usage, thereby achieving efficient performance in bandwidth‐constrained network environments.

Joint 2‐D LFM Modulation and Mismatched Filter Design in Dual‐Function Radar‐Communication System

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper proposes a joint 2‐D LFM modulation and mismatched filtering design for military‐grade dual‐function radar‐communication systems. The novel scheme modulates data onto both the initial frequency and chirp rate of LFM pulses, boosting data rates whilst preserving the constant‐envelope property critical for high‐power transmission.
