In the new scheme non-DC biased optical OFDM (NDC-OFDM) and optical spatial modulation (OSM) methods are combined to obtain a novel optical OFDM scheme which has a better error performance. The new scheme is named as non-DC biased optical spatial modulation OFDM (NDC-OSM-OFDM). It is shown via computer simulations that the proposed scheme achieves better bit error rate (BER) performance than DC-biased optical spatial modulation OFDM (OSM-OFDM-DC) asymmetrically clipped optical spatial modulation OFDM (OSM-OFDM-AC) and NDC-OFDM. © 2016 IEEE.trinfo:eu-repo/semantics/openAccessMIMO systemsOFDMOptical Spatial Modulation (OSM)Visible Light Communications (VLC)Conference Object1073107610.1109/SIU.2016.74959292-s2.0-84982840853N/AN/A
