An Efficient Encoder-Subcarrier Mapping Method Combined With Polar Code for Visible Light Communication

A spectral efficient light emitting diode (LED)-based visible light communication (VLC) system adopting polar-coded 128 quadrature-amplitude modulations (QAM) orthogonal frequency division multiplexing (OFDM) is experimentally demonstrated. To overcome frequency fading in the VLC system, an encoder-...
