© 2022 IEEE.In this study, it is planned to use the optical OFDM (NDC-O-OFDM) method, which does not use DC bias addition, as a solution to the energy inefficiency problem of the DCO-OFDM system, which is one of the most important and spectrum efficient optical OFDM techniques for visible light communication (VLC) systems. In order to increase the performance of the NDC-O-OFDM system, the use of channel coding techniques such as Reed Solomon (RS) and 1/2 rate convolutional coding (CC) is recommended in this study. Numerical simulation studies are carried out to verify the performance of this proposed new channel coded waveform in the optical MIMO channel environment and to compare it with other optical OFDM systems. From the produced numerical results, it is understood that it is achieved approximately 6.5 dB SNR gain without sacrificing energy efficiency with the proposed channel-coded NDC-O-OFDM waveform against the un-coded NDC-O-OFDM and un-coded DCO-OFDM waveforms.
