AN ANALOG MODULATOR FOR 460 MB/S VISIBLE LIGHT DATA TRANSMISSION BASED ON OOK-NRZ MODULATIONHONGLEI LI, XIONGBIN CHEN, JUNQING GUO, ZONGYU GAO, AND HONGDA CHEN.Wireless Communications:April 2015,Volume:22 , Issue: 2,68-73摘要下载全文This article describes an analog modulator that contains modulation, a MOSFET drive, and pre-emphasis circuits for a high-speed VLC application system based on a commercial phosphorescent white LED. We propose a small signal modulation model that is implemented by an AC-coupled N-channel MOSFET circuit and present a pre-emphasis circuit to enhance the 3 dB bandwidth of a VLC link. Utilizing our proposed analog modulator combined with blue filtering, the 3 dB bandwidth of a VLC system could be extended from 3 to 175 MHz, which allows OOK-NRZ data transmission up to 460 Mb/s with BER below 10-9 under a 1 m radial distance. With a simple analog modulator based on the simplest OOK-NRZ modulation scheme, a high-speed VLC system could be realized. The VLC link with the proposed analog modulator is a good solution for a high-speed low-complexity and low-cost practical VLC application system.
High Bandwidth Visible Light Communications Based on a Post-Equalization Circuit
Honglei Li, Xiongbin Chen, Beiju Huang etc..PHOTONICS TECHNOLOGY LETTERS:JANUARY 15, 2014,VOL. 26, NO. 2,,119-122摘要下载全文A research in extending bandwidth of the visible light communication (VLC) system that uses phosphorescent white LED has been reported in this letter. Slow response of the phosphorescent component limits the modulation bandwidth of white LED to the lower MHz range. In this letter, we present a post-equalization circuit that contains two passive equalizers and one active equalizer. With blue-filtering and the post-equalization circuit, a bandwidth of 151 MHz has been achieved in our VLC system, which allows OOK-NRZ data transmission up to 340 Mb/s. The VLC link operates at 43 cm using a single one Watt white LED, and the bit-error-ratio was below 2 × 10−3, which is within the forward error correction limit.

Design of Indoor Wireless Communication System Using LEDs
Yu Yang, Xiongbin Chen, Lin Zhu, Bo Liu and Hongda Chen.ACP2009:2009,Proc. SPIE 7632, 76321L摘要下载全文An indoor wireless communication system using commercial white LED is presented in this paper. OOK (On-Off Keying) modulation is adopted in the transmitter module. Data transmission is realized based on RS-485 protocol. A DC-balanced coding with error check and correction abilities is applied to avoid blinks and improve the performance of the system. The system can keep 10-7 error bit rate within 2.5m reach at a rate up to 115200 bps.
