The dual superposition multiplexing (DSPM) operation passively adds two low signal modulation format-encoded complex numbers and assigns the sum to subcarrier index-power modulation (SIPM)-generated low and high power subcarriers. Detailed numerical explorations of SIPM-OOFDM-DSPM performances over additive white Gaussian noise (AWGN) channels are undertaken, based on which optimum key transceiver parameters are identified. In comparison with previously published techniques, over simple DML-based IMDD PON systems, SIPM-OOFDM-DSPM considerably improves the signal transmission capacity, system power budget and performance tolerance to both chromatic dispersion and fiber nonlinearity.
