Abstract
In this letter, we consider a recently introduced doubly inverted Gamma-Gamma (IGGG) turbulence channel model and analyze the performance of a multi-hop unmanned-aerial-vehicle (UAV)-based free space optics (FSO) communication system assuming a decode-and-forward (DF) relaying strategy. UAV-based FSO communication improves wireless connectivity, allowing flexible deployment to establish a line-of-sight (LoS) communication with ground-based nodes. The channel modeling incorporates atmospheric turbulence, non-zero boresight pointing errors, path loss, and angle of arrival (AoA) fluctuations. The closed-form expressions for the outage probability (OP), average bit error rate (ABER), and ergodic capacity (EC) are derived over the IGGG turbulence channel with non-zero boresight pointing errors. In addition, the diversity gain and outage/BER floor are calculated from the asymptotic analyses. To validate all the analytical expressions, Monte-Carlo simulations are conducted utilizing the IGGG turbulence channel model.
期刊介绍:
The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
