Recent advancements in free-space optical(FSO) communications have allowed it
to emerge as a viable alternative to today's wireless connections. FSO has been
proposed to be a mean of signi cantly increasing bandwidth and reliability in
wireless connections. The motivation is to understand the performance of Hybrid
FSO/RF in dual-hop(DH) with decode and forward(DF) and cooperative
DF relaying and direct link scenarios.
In this thesis, we discuss the bene ts and reasons of using a hybrid FSO/RF system
in DH and selection combining(SC) scenarios. We derive the mathematical
expressions for outage probability of the hybrid FSO/RF system in three di erent
scenarios, which are given as follows: 1. single link 2. DH with DF relaying, and
3. cooperative DF relaying with direct link considering SC. We also present the
Monte-Carlo simulation results to validate the derived analytical outage probability
expressions. Both numerical and simulation results are discussed to show
the implications of using Hybrid FSO/RF system in di erent weather conditions.
The simulation results show an improvement in the outage performance of hybrid
FSO/RF system compared to the performance of FSO system.
We also present the simulations of average bit error rate(BER) in both DH and
SC scenarios and analyze the performance of hybrid FSO/RF considering di erent
SNR values of RF and FSO links. From the simulation results, it can be
inferred that the BER performance of the hybrid FSO/RF system is better than
the performance of FSO system. |
