A Cost-Effective and Efficient Scheme for Optical OFDM in Short-Range IM/DD Systems

We propose a cost-effective and efficient modulation scheme for intensity-modulated and direct-detection (IM/DD) optical orthogonal frequency division multiplexing (O-OFDM) systems, which combines complex-to-real transform (C2RT) and fast Hartley transform (FHT), named as fast-fast Fourier transform...
