    The performance of single carrier and OFDM is compared when nonlinear compensation at the DSP receiver is employed. We show that the joint use of RF-pilot and back-propagation adds further improvement to OFDM performance.
  • Digital pre-emphasis for 10Gb/s with low-cost directly phase-modulated lasers for PONs

    We apply digital pre-emphasis to compensate for the frequency response non-idealities of low-cost optical transmitters. It enables transmission beyond 10Gb/s with 2/4/8-DPSK using directly modulated lasers and coherent ...
