Performance of the Dynamic Range Limited Optical OFDM Schemes with Error Correction Coding

Optical wireless communication is a potent technology for future indoor and outdoor communication. Currently unipolar OFDM schemes have been introduced to compensate for the limitation like inter symbol interference and multipath fading. This work presents the error correction coding for unipolar OFDM schemes to improve the BER performance. In particular, hamming code was used to improve the BER vs LED dynamic range performance. Finally results, from simulation, reveals the improvement of the coded optical OFDM schemes with un-coded optical OFDM schemes.
