Abstract

We demonstrate the performance advantage of multi-beam terrestrial free-space optical communication links over single-beam links in the presence of strong optical turbulence. We adapt a space-time block code proposed for RF wireless systems to be used with intensity-modulated optical signals, and find that significant signal-to-noise ratio gains are obtained by using a four-beam link over a single-beam link with the same total electrical power.
