      We investigate the joint implementation of back-propagation and RF-pilot tone for fiber nonlinear compensation in POLMUX-16QAM and show that the nonlinear tolerance is drastically improved when compared to OFDM system
    • Comparison of single carrier and OFDM with back-propagation and RF pilot tone for a 9x224Gb/s POLMUX-16QAM system

      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.
