Adaptive Unipolar MIMO-OFDM for Visible Light Communications

2019 European Conference on Networks and Communications (EuCNC), 2019
Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for U-OFDM systems by applying adaptive transmission over realistic VLC links.
