W. Huang et al., ATMOSPHERIC OPTICAL COMMUNICATION-SYSTEM USING SUBCARRIER PSK MODULATION, IEICE transactions on communications, E76B(9), 1993, pp. 1169-1177
Atmospheric optical communication (AOC) system using subcarrier PSK mo
dulation is proposed and its superiority to OOK modulation in the pres
ence of scintillation is discussed theoretically. An experimental AOC
setup with a subcarrier modulated by 155.52 (Mb/s) DPSK at light wavel
ength lambda=0.83(mum) over an 1.8(km) outdoor path is employed to sho
w the performance. Theoretical and experimental results are compared u
nder scintillation in clear weather and a good agreement is observed.
Finally, AOC systems using subcarrier M-ary PSK and multiple subcarrie
rs are proposed and discussed.
