Partition-Based Probabilistic Shaping for Fiber-Optic Communication Systems


Abstract:

Various aspects of distribution matchers (DMs) with constant and variable composition are reviewed. LDPC-coded fiber simulations of 64QAM shaped via a multiset-partition DM show significantly increased reach and information rate over a constant-composition DM.
