Abstract :
In this invited paper, we describe an LDPC-coded turbo equalization scheme, as a universal scheme that can be used for simultaneous mitigation of: (i) fiber nonlinearities, (ii) PMD, (iii) PDL, (iii) chromatic dispersion, and (iv) I/Q-imbalance effects in multilevel coded-modulation schemes.
