English Abstract
Free space optical communication systems are able to complement or replace radio frequency systems because of their great bandwidth, license free spectrum and robustness to signal interference,yet, performance of FSO links faces an atmospheric turbulence-induced fading that known as scintillation, which eventually degrades the performqnce of the FSO system.
Moreover, FSO links encounter weak earthquakes, active wind loads that result in the shaking of the transmitter laser beam resulting in misalignment between the transmitter and the receiver “pointing errors”.
A trackable probability density function (PDF) is significant for studying the random irradiance instabilities in FSO links.
Knowing the PDF is important to find other statistical metrics for measuring the link performance like the bit error rate (BER), outage probabilty (OP).
In the history of PDF, the most models that proved to be effective are; the Lognormal (LN), Gamma-Gamma (GG), Double Weibull (DW), and the K distribution.
For moderate to strong turbulence severity, Double Weibull channel model is considered to be the msot approriate model to can describes the flactuations of the received signal irradiance.
In this thesis, we consider the performance of a single link free space optical system operting over Double Weibull atmospheric turbulence channel with pointing error.
To evaluate the system performance, we derived closed expressions to decribe the performance of three system metrics; outage probability, bit error rate and outage capcity.
Furthermore, the three system metrics are derived and evaluated for two system setups.
The first system uses differentially encoded phase - shift keying with heterodyne detection, while the other system uses intensity modulation with direct detection.
Finally, the results are shown for the three system metrics by taking into account the effect of turbulence conditions and poiting error.
