The subject that is presented in this thesis is a review on indoor optical
wireless communication systems, concentrating on specific issues, apart from a
general review of how such systems work. Modeling these systems is an important
part of the research on them, since they provide a good idea of their expected
performance. The usual spectrum in which they operate is the infrared light,
even though the later advances in white light LED production turned researchers
to the possibility of using the visible spectrum.
Indoor optical wireless systems may substitute or work alongside common
RF systems. In comparison to RF, OW systems have certain advantages, but do
show certain difficulties as well. OW systems are simple to install, cheaper,
without any need to buy license for the use of certain spectrum as is the case
for RF. Moreover, higher data rates can be achieved, there are no interference
from common RF systems and are safer in terms of data stealing or overhearing
from a distance.
Moreover, presented in this thesis are applications, topologies,
advantages and disadvantages of technologies. The use of optical MIMO
techniques is also presented, a technique that helps in solving many issues and
improves performance of such systems.
