Improving performance in free space optical communication (FSOC) channel through the dual diffuser modulation (DDM) due to atmospheric turbulence

Abdul Rahman, Kram; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Anuar, Mat Safar, Ir. Dr.; Hilal Adnan, Fadhil, Dr. (Asian Research Publication Network, 2014-02)

This paper focus on reduction of atmospheric turbulence effect on free space optical communication using robust modulation that is dual diffuser modulation (DDM) technique. This technique uses two transmitter and differential ...

Enhance the performance of free space optical (FSO) communication due to atmospheric turbulence via the dual diffuser modulation (DDM)

Abdul Rahman, Kram; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Anuar, Mat Safar, Ir. Dr.; Hilal Adnan, Fadhil, Dr. (Trans Tech Publications, 2013-12)

This paper focus on mitigating the atmospheric turbulence effect in free space optical communication using dual diffuser modulation (DDM) technique. Phase screen diffuser located on transmitter create 'new' beam wave to ...
