Improving Performance for DCO-OFDM Based VLC via Convolutional Coding and Viterbi Decoding

The reliability of Visible Light Communication (VLC) is affected by several parameters, the most significant being high peak-to-average power ratio(PAPR) and nonlinear distortion. This study presents an adaptive direct current O-OFDM (DCO-OFDM) based VLC system as a solution, which integrates error correction the Convo...

LED dimming and nonlinearity effects on link selection in hybrid VLC/RF networks

Abstract The codeployment of visible light communication (VLC) and radio frequency (RF) technologies has attracted research interest for indoor capacity enhancement. Many existing hybrid VLC/RF link selection schemes assume that the LED behaves as a perfectly linear device, an assumption that fails under practical dimm...
