LDPC codes for optical channels: Is the "FEC limit" a good predictor of post-FEC BER?
Paper in proceeding, 2015
We answer the question in the title negatively. More precisely, the FEC limit is invalid for soft decision decoding and low to medium code rates. A better predictor is the generalized mutual information.
