Özet
Applying the drone-based free space optical (FSO) technology is recent in
communication systems. The FSO technology has high-security features due
to narrow beamwidth, insusceptible to interferences, free license, and
landline connection is not appropriate. However, these advantages face many
obstacles that affect the system's performance, such as random weather
conditions and misalignment. The pointing error Hp is one of the critical
factors of the channel gain H. The related parameters of the Hp factor: the
pointing error angles θr and the path length Z, were manipulated to extract
the applicable values at various receiver diameter values. The proposed
system has two topologies: single input single output (SISO) and multiple
input single output (MISO), flying in weak atmospheric turbulence. The
simulation was done using MATLAB software 2020. The average bit error
rate (ABER) for the system versus signal-to-noise ratio (SNR) were verified
and analyzed. The results showed that at θr=10−3
rad, Z increased in the
range 10~100m for each one-centimeter increase of DR. At θr=10−2
rad, the
applicable Z was nearly 10% of the link distance Z when θr=10−3
rad was
applied. Consequently, an increase in θr must correspond decrease in Z and
vice versa to maintain the system at high performance.
