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
(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 ...
Study of the OCDMA transmission characteristics in FSO-FTTH at various distances, outdoor
(De Gruyter, 2013-06)
It is important to apply the field Programmable Gate Array (FPGA), and Optical Switch technology as an encoder and decoder for Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) Free Space Optic ...
Impact of multi-diagonal code on high-speed spectral amplitude coding optical code division multiple-access networks
(Springer-Verlag, 2013-09)
In this paper, we present the impact of the multi-diagonal (MD) code for high data rate in spectral amplitude coding optical code division multiple-access (SAC-OCDMA) networks. An MD code structure for SAC-OCDMA system is ...
Improvement of the bit error rate of a non-coherent OCDMA system for FTTH network applications
(Springer Verlag, 2013-12)
In this paper, an optical code division multiple access (OCDMA) system was analysed to improve the bit error rate (BER) performance at 10 Gbps. The improvements to this system were based on a modified double weight code ...
