| Summary |
Light-emitting diode (LED) transmitters based optical
wireless communication (OWC) systems offer the potential
for new generation communication systems. Particularly, an
image sensor based OWC systems consist of the LED transmitters
and camera receivers are expected to contribute to intelligent
transport system (ITS) for driving supports. For high achievable
data rates, orthogonal frequency division multiplexing (OFDM)
based OWC systems have attracted a great deal of attention.
Despite attractive features of optical OFDM, only few attempts
have so far been made to adopt it as a modulation scheme of
an image sensor based OWC system. There remains a need
for an evaluation of adopting an optical OFDM to the image
sensor based OWC systems. Another important issue needs to
be addressed is the performance degradation due to a frequency
response of an actual image sensor device, especially a signal
attenuation loss in higher frequency. In addition to such loss, a
narrow band noise generated by its circuits also degrades the
performance. The purpose of this paper is to investigate BER
performances of the optical-OFDM using an actual image sensor
device, the optical communication image sensor (OCI). From
simulation results, it is found that the frequency response and the
narrowband noise at 12MHz of the OCI lead to the significant
reduction of BER performances. Additionally, the results shows
that ACO-OFDM shows a little better performance compared to
DCO-OFDM with the same bandwidth efficiency. |
