This report presents the
analysis of different modulation schemes D4.1 for VLC systems
of
the VIDAS project.
Considering the final
prototype design and
application, the
deliverable D4.1 was projected.
The
detail analysis of various modulation schemes are carried out and a robust technique
based on direct sequence spread spectrum (DSSS) is followed. DSSS technique though
necessitates use of high bandwidth while minimizing the effect of noise. Since the final
application does not require very high dat
a rate of transmission but robustness against the
noise (external lights)
becomes necessary. The analysis is followed by model development
using Matlab/Simulink.
The performance of both of these systems are compared and
evaluated.
Some of the simulation
results are presented
