Achievable Rate Comparison Between Entropy and Bit Loading in a 100-Gb/s DM-DD DMT System
01 January 2019
We propose an efficient entropy loading (EL) scheme with NGMI target based on lookup tables. We reveal the EL superiority on channel coding over bit loading in a 100-Gb/s DMT system, proving EL as the optimum capacity-approaching modulation for band-limited transceivers.
