Reducing Turbulence-Induced Outages in a Deployed Terrestrial Free-Space Optical Communication Link via Interleaving
For free-space optical communication systems, this work provides a practical method to mitigate turbulence-induced outages, though it is an incremental application of interleaving to a specific domain.
The study demonstrates that data interleaving reduces outage probability by two orders of magnitude in a 4.6 km terrestrial free-space optical link, revealing a dependency between turbulence strength, interleaver length, and data rate for robust system design.
We present an experimental study of data interleaving for terrestrial free-space optical communication over a 4.6~km urban testbed. Results demonstrate a two-order-of-magnitude reduction in outage probability. A dependency between measured turbulence strength, interleaver length, and achievable data rate is revealed, enabling robust system design.
