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.
