Physical layer security in satellite communication: State‐of‐the‐art and open problems

IET Communications, Volume 19, Issue 1, January/December 2025.
This paper first classifies contemporary satellite communication networks into five domains and then analyse the use of PLS in each domain; these domains are hybrid satellite‐terrestrial networks, satellite‐based IoT, navigation satellite systems, FSO‐based satellites, and inter‐satellite communications.

Relay‐Assisted Communications Over Multi‐Cluster Fluctuating Two‐Ray Faded Channels

IET Communications, Volume 19, Issue 1, January/December 2025.
A decode‐and‐forward relay‐assisted device‐to‐device (D2D) network is examined over novel multi‐cluster fluctuating two‐ray fading channels. All communication links are functioning in terahertz (THz) conditions. Co‐channel interference (CCI) is considered as well.
