Description
This paper scrutinizes visible light communication (VLC) employing hybrid
optical time division multiplexing (OTDM) wavelength division
multiplexing (WDM). It also demonstrates the simulation of VLC using the
direct sequence optical code division multiple access (DS-OCDMA) system
developed by OptiSystem-Matlab Co-simulation. The profits of WDM and
OTDM capacities have been combined using two levels of freedom to build
up of the system. The performances are demonstrated in the simulated
findings of the bit error rate (BER) in relationship with the data rate and the
number of users. First, the simulated results display the usefulness of the
system. Then, the number of users has been significantly enhanced. Besides,
the OCDMA functions by appointing a specific code to each user and could
provide asynchronous and simultaneous access to numerous users. One
drawback is multiple access interference (MAI). The use of very long code
sequences is crucial in order to lessen this effect. Hence, very large
bandwidths are essential. This study aims at demonstrating, through system
simulation, the practicability of an all-optical conventional correlation
receiver dedicated to a DS-OCDMA access network link. Again,
OptiSystem has been used to realize our blocks.
