摘要：
We compared the performance of the asymmetric and direct current bias limiting optical orthogonal frequency division multiplexing (ADO-OFDM), asymmetric limiting optical orthogonal frequency division multiplexing (ACO-OFDM), and the direct current bias limiting optical orthogonal frequency division multiplexing (DCO-OFDM) in visible light communication (VLC) systems. We optimize the power ratio between ACO and DCO parts in ADO-OFDM. The results show that ADO-OFDM has better performance than DCO-OFDM at small bias value, which indicate higher power spectral efficiency. It is also shown that the BER of ACO-OFDM with 16-QA114 format is smaller than that of ADO-OFDM with 4-QA114 format.
