This manuscript proposes a new Visible-Light Communication (VLC) system
that transmits information to handheld terminals carried by pedestrians
through the use of LED backlighted signboards located in public spaces.
To improve previous systems proposed by us, we introduce the use of multilevel modulation.
Specifically, in order to avoid the effect of nonlinearity of LEDs, we
apply binary baseband modulation to LED by FET switching.
We propose a scheme that realizes multilevel amplitude modulation by
spatially combining the binary light signals.
In order to evaluate the performance, multiple LED lights and a
diffuser board are employed to set the experimental environment.
In the experiment, we found out that the duty cycle of the ON/OFF
switching of the LEDs affects the output voltage of the photoelectric
converter.
Thus, we apply a scheme that makes those duty cycles become uniform.
Consequently, 4-level amplitude modulation is achieved, and our experimental result shows that a
t a transmission rate of 5Mbps the bit error rate becomes lower than $10^{-3}$. |
