On the Channel Capacity of Multilevel Modulation Schemes with Coherent Detection

摘要：

We describe a method to determine the channel capacity of an arbitrary multilevel modulation scheme by modeling the fiber-optic channel as a dynamical nonlinear intersymbol interference (ISI) channel with memory. We also propose a multilevel low-density parity-check (LDPC)-coded turbo-equalization scheme that is able closely to approach the channel capacity.
