The increasing interest in the field of free-space optical communication (FSOC) can be attributed to the rising demand for an alternate communication system that can replace the existing communication systems. FSOC ranges from a few meters of indoor communication to a few kilometers of terrestrial range to satellite communication. The challenges posed vary in different scenarios. For indoors, major challenges are the artificial light sources, and for outdoors, it is the atmospheric channel-relat
