Abstract

We propose Geometric-Configuration Modulation (GM), a novel AO-free FSO paradigm utilizing multi-source geometric configuration encoding and active correlative decoding. GM demonstrates exceptional resistance to strong atmospheric turbulence ($D/r_{0}\sim 5$) over a 1.2 m link in preliminary experiments.
