VLC-using-OFDM
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.)

本文提供了一个分析 复杂的动态显示当前模式控制 开关电源转换器。电流型控制的提高 转换器与非线性分析和研究 离散建模方法已被使用。通过改变 电路参数、混乱和复杂的行为 分歧发生在开关电源转换器。为 增加稳定period-l操作范围,坡道 已经被改变其使用和补偿方法 转换器的边坡,其效果将被显示。最后, 最大平均Iyapunov指数不同的斜坡上 审查和模拟。(The present article provides an analysis of
complex dynamics displayed by current mode controlled
switching dc-dc converter. Current-mode controlled boost
converter has been studied with nonlinear analysis and the
discrete-time modeling approach has been used. By changing
circuit parameters, complex behaviors like chaos and
bifurcation occur in the switching dc-dc converter. For
increasing stable period-l operation range, the ramp
compensation approach has been used and by changing its
slope, its effect in the converter will be shown. Finally, the
largest average Iyapunov exponent for different slopes is
reviewed and simulated)
