Future work

Since this dissertation had a limited time duration, some topics could not be investigated. So, some topics are suggested for future work:

 Study the impact of fiber nonlinearities on the system. Evaluate if the DPostD algorithm MP can mitigate some of these nonlinearities.

 Evaluate the system performance when the EAM distortion is higher, for example when the signal at the EAM input does not have the optimum characteristics of RMS and bias voltage, in order to assess if the DPostD algorithm can mitigate the EAM distortion. This may involve searching different MP structures.

 Experimental demonstration of the system performance improvement in the 112 Gb/s MB-OFDM signal when DPostD based on MP is employed to mitigate the SSBI term.
