1.2 Gbit/s visible light transmission based on orthogonal frequency-division multiplexing using a phosphorescent white light-emitting diode and a pre-equalization circuit
Chinese Optics Letters, 2015Co-Authors: Xingxing Huang, Zhixin Wang, Siyuan Chen, Yiguang WangAbstract:We propose a two-cascaded, constant-resistance, symmetrical bridged-T amplitude equalizer for a high-speed visible light communication (VLC) system. With the pre-equalization circuit, the -3 dB bandwidth of the VLC system can be extended from 12 to 235 MHz using a commercially available phosphorescent white light-emitting diode (LED), a blue filter, and a low-cost PIN photodiode. The Data Rate is 1.20 Gbit/s, exploiting 16-quadrature amplitude modulation-orthogonal frequency-division multiplexing with a 300 MHz modulation bandwidth over 50 cm of free-space transmission under the pre-forward error correction limit of 3.8 \times 10-3. To our knowledge, this is the Highest -3 dB bandwidth and the Highest Data Rate ever achieved by using a pre-equalization circuit and white LED in a VLC system.

Optics Express, 2015Co-Authors: Xingxing Huang, Zhixin Wang, Yiguang WangAbstract:We proposed a cascaded amplitude equalizer used for high speed visible light communications (VLC) system.

8-Gb/s RGBY LED-Based WDM VLC System Employing High-Order CAP Modulation and Hybrid Post Equalizer
IEEE Photonics Journal, 2015Co-Authors: Yiguang Wang, Xingxing HuangAbstract:In this paper, for the first time, we propose the use of a hybrid post equalizer in a high-order carrierless-amplitude-and-phase-modulation-based visible light communication (VLC) system. The hybrid equalizer consists of a linear equalizer, a Volterra-series-based nonlinear equalizer, and a decision-directed least mean squares equalizer to simultaneously mitigate the linear and nonlinear distortions of the VLC system. A commercially available red-blue-green-yellow light-emitting diode (RBGY LED) is utilized for four-wavelength multiplexing. By the hybrid equalizer, an aggregate Data Rate of 8 Gb/s is experimentally achieved over a 1-m indoor free-space transmission with the bit error Rate (BER) below the 7% forward error correction (FEC) limit of 3.8 × 10-3. To the best of our knowledge, this is the Highest Data Rate ever reported in high-speed VLC systems.
