Signal processing algorithms improve turbulence in free-space optic tests

Posted by in categories: information science, internet

New signal-processing algorithms have been shown to mitigate the impact of turbulence in free-space optical experiments, potentially bringing “free space” internet a step closer to reality.

The team of researchers, from Aston University’s Aston Institute of Photonic Technologies and Glasgow University, used commercially available photonic lanterns, a commercial transponder, and a to emulate turbulence. By applying a successive interference cancelation algorithm, they achieved record results.

The findings are published in the Journal of Lightwave Technology.
