Abstract: As an improved variant of a previously published subcarrier index-power modulated optical orthogonal frequency division multiplexing (SIPM-OOFDM), a signal transmission technique termed SIPM-OOFDM with subcarrier grouping (SIPM-SG-OOFDM) is proposed and investigated for the first time.… read more here.
