In this letter, we show that using blue filtering in combination
with simple receiver equalization, a bandwidth of 50 MHz and
data link operating at 100 Mb/s (OOK-NRZ) can be achieved.
Such a link is straightforward to implement, and provides an alternative
approach to the DMT reported in [5]. The advantage
over the technique reported in [6] is that both the blue filtering
and equalization are at the receiver, so that complex drive electronics
that must be used for every illumination LED is not required.
A typical application for such a link is data broadcasting,
where a room is illuminated by LEDs that also transmit data.
In this case, a large number of LEDs is required, so removing
complex drive electronics at the LED simplifies the system significantly
