Abstract: The Adaptable Pulse Position Modulation (APPM) optical communication system and process facilitate wireless communications through turbid mediums including, but not limited to, smoke, airborne dust, mist, fog, clouds, water, seawater and water-to-air (air-to-water) interfaces by controlling the signal gain at the optical detector and controlling of the signal encoding to allow high data rate operation when the signal to noise ratio is high. The system also supports signal encoding redundancy to maintain good connectivity at the cost of the communication channel data rate as the signal to noise degrades.
