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 ...

Comparison of single mode fiber and multimode fiber in deployment of SCM-OCDMA in local area network

Aliaa Mamoun, Kabbour; Hilal Adnan, Fadhil, Dr.; Angela, Amphawan; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Mohammad K.H., Al Mustafa (Trans Tech Publications, 2013-12)

The integration of heterogeneous technologies promotes ubiquity and mobility. Optical code division multiple access (OCDMA) may be deployed in conjunction to SCM to improve the spectral efficiency and enhance the data rate ...
