Abstract :
In this work, the DSP equalizer complexity is analyzed as a function of the modal dispersion and the number of supported modes of a few-mode fiber. It is shown that a training symbol based scheme such as OFDM is virtually unaffected by the increasing number of modes, whereas for blind FDE/TDE equalization the complexity drastically increases.
