  • NRN024 - Stage-dependent minimum bit resolution maps of full-parallel pipelined FFT/IFFT architectures incorporated in real-time optical orthogonal frequency division multiplexing transceivers

    IET Digital Library

    • Sensors and Devices, 
    • Modelling

    Fast Fourier transform (FFT) and inverse FFT (IFFT) are the fundamental algorithms at the heart of optical orthogonal frequency division multiplexing (OOFDM) transceivers. The high digital signal processing (DSP) complexity has become one of the most significant obstacles to experimentally demonstrating real-time high-capacity OOFDM transceivers. In this study, extensive numerical explorations are undertaken, for the first time, of the impacts of each individual transceiver DSP element on the inverse error vector magnitude (IEVM) performance of the OOFDM transceivers incorporating full-parallel pipelined FFT/IFFT architectures

  • NRN024 - RSOA Intensity Modulator Frequency Chirp-enhanced Optical OFDM PON Performance

    IEEE Xplore

    • Sensors and Devices, 
    • Modelling

    This paper suggests that significantly relaxed requirements on both RSOA-IM's 3-dB small-signal modulation bandwidth and frequency chirp are feasible for achieving desired OOFDM transmission performances for next-generation PONs.
