Abstract :
Presented is an extended technique for orthogonal frequency division multiplexing (OFDM) transmission with a constant envelope and optical carrier suppression. This allows a reduction of error vector magnitude at higher optical modulation index when compared to the conventional or constant envelope OFDM.
