In order to improve the spectrum and power efficiency in Visible Light Communication(VLC) and location system
we propose an Asymmetrically Clipped and DC-biased Optical-Orthogonal Frequency Division Multiplexing(ADO-OFDM) technique
which combines the advantages of Asymmetrically Clipped Optical-OFDM(ACO-OFDM) and DC-biased Optical-OFDM(DCO-OFDM) with higher spectrum efficiency than ACO-OFDM and higher power efficiency than DCO-OFDM. We also apply a differential correction location algorithm
which has higher positioning accuracy than the traditional three-side location algorithm.
