Radio frequency (RF) spectrum is highly occupied and adding further broadband channels
to fulfill the exiting user requirements has become difficult. Optical free-space …

Increased capacity, higher data rate, decreased latency, and better service quality are
examples of the primary objectives or needs that must be catered to in the near future, ie …

Hybrid free space optics/radio frequency (FSO/RF) communication has been considered as
a promising solution for reliable wireless backhaul connectivity for 5G and beyond wireless …

Nowadays, unmanned aerial vehicle (UAV) communication systems are commonly
considered as one of the key enabling technologies for 6G. The hybrid free space optical …

This paper presents a secrecy performance analysis of a parallel free-space
optical/millimeter-wave (mm-wave) communication system with a selection-combining …

In this paper, the secrecy performance of the physical layer security (PLS) of the hybrid free-
space optical/radio frequency (FSO/RF) communication system is analyzed. The …

In this paper, we introduce a decode-and-forward multi-hop hybrid free-space optical/radio
frequency (FSO/RF) system. The FSO link is assumed to follow Gamma-Gamma distribution …

Due to the influence of the atmospheric environment and pointing errors, the performance of
free space optical communication is greatly limited. In this paper, we propose a parallel multi …

Wind energy, one of the most sustainable renewable energy sources, has been extensively
developed worldwide. However, owing to the strong regional and seasonal differences, it is …

To improve the performance of fee-space optical communication systems, this paper
analyzes the performance of a relay-aided hybrid fee-space optical (FSO)/radio frequency …
