The inherent robustness of OFDM against
multipath effects makes it an excellent choice for situations
where multiple transmitters are used simultaneously (to avoid
shadowing effects) and a path difference to the receiver exists.
One of the major disadvantages of an OFDM based system is
the characteristic high crest factor of the time domain signal.
In traditional RF based systems, this usually necessitates a
transmitter with a high dynamic range and hence results in
reduced power efficiency. In the proposed optical LED system,
this disadvantage is turned to an advantage - the time domain
OFDM signal is used to modulate (IM-DD) the optical source.
