Study on Nonlinear Visible Light Communication System based on Sigma-Delta Modulation
摘要
Abstract
In Visible Light Communication (VLC) system, the modulation bandwidth of Light Emitting Diode (LED) is limited by the transmit rate.In addition, the nonlinearity in the LED limits the overall throughput of the VLC system.In order to solve the problem of the nonlinearity in the LED in OFDM VLC with high peak-to-average power ratio, a one-bit sigma-delta modulator for nonlinear visible light communication systems is proposed.Studies show that the one-bit sigma-delta modulator can significantly improve spectral efficiency and the VLC system performance with OFDM modulation.关键词
