Abstract

We experimentally demonstrate a turbulence-resilient 12-Gbit/s 16-QAM FSO link using pilot-assisted self-homodyne (rather than heterodyne) detection. Results show link resilience under 400 random turbulence realizations and up to ~20-dB improvement of optical-to-electrical mixing efficiency compared to conventional LO-based coherent detection.
