Impact of DFE on Soft-Input LDPC Decoding for 50G PON
DFE induced error correlation and mutual information (MI) degradation penalize the 50G PON LDPC code soft-input decoding performance. Bit-interleaving across multiple codewords mitigates the correlated error penalty, but not the MI degradation penalty.
