Abstract :
An atmospheric optical communication (AOC) system using subcarrier phase shift keying (PSK) is proposed, and its superiority to OOK in the presence of scintillation is discussed theoretically. An experimental AOC setup using a subcarrier modulated by 155.52 Mb/s phase differential shift keying (DPSK) at light wavelength λ = 0.83 μm over an 1.8 km outdoor path is employed to show the performance. Theoretical and experimental results are compared under scintillation in clear weather. Good agreement is observed. BER in various kinds of weather is given. AOC using subcarrier M-ary PSK and multiple subcarriers is discussed
