  • Abstract
    In this paper the authors discuss the feasibility of a constant envelope optical OFDM based on fast Hartley transform. The digital signal processing output drives an optical phase modulator for obtaining a 0 dB PAPR signal at the transmission side, whereas the use of a Hartley transform increases power efficiency and relaxes the level of the constellation used. Additionally, a set of simulations of the system are presented, showing a back-to-back sensitivity of -34.6 dBm for a 10-3 BER.
