摘要：This paper focus on mitigating the atmospheric turbulence effect in free space optical communication using a dual diffuser modulation (DDM) technique. The most deteriorate the FSOC is scintillation where it affected the wave front cause to fluctuating signal and ultimately receiver can turn into saturate or loss signal. DD approach enhances the detecting bit 1 and bit 0 and improves the power received to combat with turbulence effect. The performance focus on Signal-to-Noise (SNR) and Bit Error Rate (BER) by using the Kolmogorovs scintillation theory. The numerical result shows that the DD approach improves the range where estimated approximately 40% improvement under weak turbulence and 80% under strong turbulence.
