The theoretical analysis of the bit error rate(BER)performance in a discrete Hartley transform(DHT)post-coded or-thogonal frequency division multiplexing(OFDM)visible light communication(VLC)system over an additive white Gaussian noise(AWGN)channel is presented.The theoretical analysis results show that the proposed DHT post-coding scheme does not degrade the BER performance of the post-coded OFDM VLC systems.The analysis re-sult is confirmed by our simulation results for random bit source.In addition,the peak-to-average power ratio(PAPR)of the DHT post-coded OFDM is evaluated by simulation.The simulation results show that DHT post-coding can greatly reduce of the PAPR of the optical OFDM system.
