Abstract

The conventional modulation that is on- off keying (OOK) is suffered from the threshold detection level. This condition is worst with the presence atmospheric turbulence. The new modulation technique which based on dual carrier modulation enhance the performance FSO transmission with offering high power received and low scintillation index. The finding results show that under the strong turbulence condition the propagation distance can improve approximately 61% percent in comparison with conventional technique. Meanwhile for comparison wavelength the 1550 nm shows better performance than 850 nm where the improvement approximately 16% percent.
