Abstract.  On bandwidth-limited visible light communication (VLC) transmission systems, direct current (DC) component loss, DC-unbalance of code, and severe high-frequency attenuation cause baseline wander (BLW) and data-dependent jitter (DDJ) phenomena, which deteriorate signal quality and result in a higher bit error rate (BER). We present a scheme based on hybrid run length limited codes and pre-emphasis techniques to decrease the intersymbol interference caused by BLW and DDJ phenomena. We experimentally demonstrate, utilizing 1-binary-digit-into-2-binary-digits (1B2B) codes and postcursor pre-emphasis techniques, that the impacts of BLW and DDJ on on–off keying nonreturn-to-zero VLC systems are alleviated and a 130  Mb/s data transmission rate with a BER performance of <104 can be achieved.
