说明: 将OFDM技术运用在可见光通信的研究,并且把OFDM的高峰均比这一缺点进行了建设性的运用。
(In
particular, the use of OFDM (orthogonal frequency division
multiplexing) for intensity modulation is investigated. The high
peak-to-average ratio (PAR) in OFDM is usually considered
a disadvantage in radio frequency transmission systems due
to non-linearities of the power amplifier. It is demonstrated
theoretically and by means of an experimental system that the
high PAR in OFDM can be exploited constructively in visible light
communication to intensity modulate LEDs. It is shown that the
theoretical and the experimental results match very closely, and
that it is possible to cover a distance of up to one meter using a
single LED.)
