Simultaneous dimming controlling and data transmission are usually required in a white
LED based indoor visible light communication system. However, the diming controlling of …

In visible light communication, it is difficult to control dimming of LED lamp or flicker occurs
due to changes in luminous flux according to the data. In this paper, to solve this problem …

We investigate the performance of visible light communication (VLC) system with a pulse
width modulation (PWM) dimming control scheme. Under this scheme, the communication …

In traditional dimming control system using pulse width modulation (PWM) combined with M-
QAM OFDM scheme, OFDM signal is only transmitted during “on” period. To guarantee the …

This letter proposes a practical scheme for LED dimming control in visible light
communications (VLC). The scheme entails the allocation of a set of codewords to a symbol …

(in English) An indoor visible-light communication system utilizing LED light is proposed.
However, the performance of each modulation method is not clarified. In this paper, we …

A visible light communication system using white light emitting diode (LED) has been
proposed and demonstrated, in which the transmitter and receiver of visible light …

We design a hybrid visible light (VL) and infrared (IR) data transmission scheme for indoor
visible light communication (VLC) systems with multi-pulse position modulation (MPPM) …

For indoor visible light communication (VLC), much work has been done when the noise is
independent of the input signal. However, less effort is made when the VLC system suffers …

In the field of indoor wireless networks, visible-light communications is garnering increasing
attention. One of the type of emitters used in this technology is white light-emitting diodes …
