| Abstract: | Coherent optical orthogonal frequency-division multiplexing(CO-OFDM) is being considered as a promising technology which has been demonstrated to combat fiber chromatic dispersion and polarization-mode dispersion(PMD).However, owing to high peak-to-average power ratio(PAPR) and closely-packed subcarriers(tens of MHz),CO-OFDM system is quite sensitive to nonlinearity.The fiber nonlinearity for CO-OFDM system and a simple but computationally efficient nonlinearity compensation technique are introduced to impr... |
