Design Examples – Rare Scintillation Events in FSO Links
The example shown here illustrates an efficient way of simulating statistically rare scintillation events in a Free Space Optical link using Importance Sampling supported by the atmospheric channel model.
This method allows for simulating user-defined values of power fluctuations due to scintillation. The total BER is calculated through a sum with weights equal to the probabilities of these scintillation events.
Another design example simulates an FSO GEO Feeder link with FEC, illustrating the link budget analysis and exploring the pre- and post-FEC system performance.
