Free-Space Optical Communication Systems with a Partially Coherent Gaussian Beam and Media Diversity

Terrestrial free-space optical (FSO) communications is an emerging low-license-free and high-bandwidth access solution, albeit hampered by the combined effects from atmospheric loss, turbulence and pointing errors (PEs).
