Comparison among different types of advanced modulation formats under four wave mixing effects
(Ukrainian Journal of Physics., 2013)
Advanced modulation formats play a significant role for enhancing the bit rate in an optical transmission system. Ultra-long haul transmission distances are intensively investigated to further increase the spectral efficiency ...
Enhance the performance of free space optical (FSO) communication due to atmospheric turbulence via the dual diffuser modulation (DDM)
(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
