Asymmetrically clipped orthogonal frequency division multiplexing (ACO-OFDM) is one of the optical modulation techniques for indoor optical wireless communication systems (OWC) to enable intensity (IM) modulation and direct detection (DD). As compared to other techniques, ACO-OFDM is power efficient, bandwidth efficient and has zero impact of clipping noise. However, its high peak to average power ratio (PAPR) may lead to performance deterioration and also introduce nonlinear distortion in optical source. To further enhance its performance by reducing the PAPR, suppressed carrier frequency division multiplexing (SC-FDM) is proposed and the system is titled as interleaved coded ACO (ICACO)-OFDM. To evaluate the performance of the system, simulation has been carried out for 16-QAM, 256 subcarriers, 1000 symbols. By observing the curves generated by Complementary cumulative distribution function (CCDF) at the probability of 10-3, PAPR has been characterized. It is observed that PAPR of ICACO-OFDM is 4.98 dB less as compared to ACO-OFDM system.

Abstract


Asymmetrically clipped orthogonal frequency division multiplexing (ACO-OFDM) is one of the optical modulation techniques for indoor optical wireless communication systems (OWC) to enable intensity (IM) modulation and direct detection (DD). As compared to other techniques, ACO-OFDM is power efficient, bandwidth efficient and has zero impact of clipping noise. However, its high peak to average power ratio (PAPR) may lead to performance deterioration and also introduce nonlinear distortion in optical source. To further enhance its performance by reducing the PAPR, suppressed carrier frequency division multiplexing (SC-FDM) is proposed and the system is titled as interleaved coded ACO (ICACO)-OFDM. To evaluate the performance of the system, simulation has been carried out for 16-QAM, 256 subcarriers, 1000 symbols. By observing the curves generated by Complementary cumulative distribution function (CCDF) at the probability of 10-3, PAPR has been characterized. It is observed that PAPR of ICACO-OFDM is 4.98 dB less as compared to ACO-OFDM system.
