N2 - In a previously published transmission technique known as subcarrier index-power modulated optical OFDM (SIPM-OOFDM), a new subcarrier index-power (SIP) information-bearing dimension is introduced to enable SIPM-OOFDM to carry one extra information bit per subcarrier. As a significantly improved variant of SIPM-OOFDM, in this paper, a novel signal transmission technique termed multi-level subcarrier index-power modulated OOFDM (ML-SIPM-OOFDM) is proposed and extensively explored, for the first time, which utilises four predefined subcarrier power levels to convey two extra information bits per subcarrier in the SIP information-bearing dimension. Extensive explorations of ML-SIPM-OOFDM transmission performance characteristics are undertaken, based on which optimum key transceiver parameters are identified. For cost-sensitive intensity-modulation and direct-detection (IMDD) passive optical network (PON) systems, it is shown that, compared to SIPM-OOFDM, ML-SIPM-OOFDM improves the signal transmission bit rate by 30%. In addition, in comparison with conventional OOFDM, a 13% increase in ML-SIPM-OOFDM signal transmission bit rate is also feasible without degrading the minimum received optical power required for achieving a BER of 1.010-3. Moreover, further 9% and 10% ML-SIPM-OOFDM signal transmission bit rate enhancements are also achievable when use is made of adaptive bit loading and subcarrier count doubling, respectively.
