—A number of unipolar optical orthogonal-frequency-division-multiplexing (OFDM) schemes have been proposed as a solution to the high energy consumption in the widely adopted direct-current-biased optical OFDM (DCO-OFDM) modulation scheme. These schemes have a reduced spectral efficiency due to the restrictions imposed on their frame structure. The enhanced(More)
Inherent unipolar orthogonal frequency division multiplexing (OFDM) schemes have a reduced spectral efficiency (SE) when compared with direct current (DC)-biased optical OFDM (DCO-OFDM). The concept of superposition modulation was proposed as a solution to the SE loss of unipolar orthogonal frequency division multiplexing (U-OFDM) and the power efficiency(More)
