This technique uses two transmitter and differential mode detection at the receiver. The combination of dual diffuser with a differential detection mode at receiver produce the superior modulation against the turbulence especially reducing the scintillation index, overcome the signal detection with fix zero threshold and improve the power received. These three element factors are important in order to improve the overall performance of free space optical system. The analysis result show that for receiving power DDM at 3km distance propagation is 4.59dBm compare with conventional OOK that using diffuser only -7.6dB which equal to 3dBm improvement or around 40 percent. Meanwhile in term of BER performance, the DDM can further the distance propagation with approximately 42 percent improvement 2014-06-19T08:31:59Z 2014-06-19T08:31:59Z 2014-02 Article Journal of Theoretical and Applied Information Technology, vol. 60 (1), 2014, pages 27-33 1992-8645 1817-3195 (online) http://dspace.unimap.edu.my:80/dspace/handle/123456789/35714 http://www.jatit.org/volumes/Vol60No1/4Vol60No1.pdf en Asian Research Publication Network
