Abstract: An apparatus and method for transmitting information bits via an optical communication system, the apparatus including a distribution matcher (DM) configured to receive information bits and to generate shaped symbols relating to the information bits; a pre-deinterleaver (PDI) coupled to the DM and configured to apply a perturbation function q(n) to the shaped symbols to produce pre-deinterleaved symbols; an error reduction processor (ERP) coupled to the PDI and configured to receive computer instructions which, when executed, prompt the ERP to produce error reduction symbols from the pre-deinterleaved symbols, the error reduction symbols being perturbed from the pre-deinterleaved symbols by a perturbation function p(n), q(n) being an inverse of p(n); and a modulator coupled to the ERP and configured to convert the error reduction symbols into optical signals configured for transmission via an optical communication system.
