Özet
The rapid development of drones that are a type
of Unmanned Arial Vehicles (UAV) in different fields
encourages researchers and institutes concern with wireless
communication to use this technology. As wireless optical
communication (OWC) has been applied and has many
advantages over Radio Frequency (RF), this enables using the
optical beam in UAV-based Free-space optical (FSO)
technology as an alternative to RF technology. In this paper,
the proposed system configuration has two subsystems: Single
Input-Single Output (SISO) and Multiple Input-Single Output
(MISO). The system was simulated using MATLAB software
2020. The optical signal was modulated using Pulse Position
Modulation (PPM) and transmitted in a weak turbulence
regime. The Average Bit error Rate (ABER) was measured
depending on the pointing error HP factor. The idea was to find
the specific values of the pointing error angle θr and link
distance Z that are the related parameters of HP. The results
have clarified that for each pointing error angle θr value, there
was a specific path length Z, which can keep the system at high
performance, for example, θr= rad, the applicable link
distance Z=1000 m, and the ABER≈
