Patent ID: 10826648

Abstract:
Methods (C) for converting a data signal (U), comprising processes of (i) providing an input symbol stream (IB) of input symbols (IBj), the input symbol stream (IB) being representative for the underlying data signal (U) to be converted, and (ii) applying a distribution matching process to consecutive partial input symbol sequences (IBk) of a number of k consecutive input symbols (IBj) covering said input symbol stream (IB). The distribution matching process (DM) generates and outputs a final output symbol stream (OB) of consecutive output symbols (OBj) or a preform thereof, wherein the distribution matching process (DM) is based on and/or comprises a family ((ƒi)i∈{0, 1, . . . , n-1}) of a number (n) of distribution matching functions (ƒi), the action of the distribution matching process (DM) is achieved by acting with one of said distribution matching functions (ƒi) selected from said family ((ƒi)i∈{0, 1, . . . , n-1}) on said partial input symbol sequences (IBk), and wherein selecting a distribution matching function (ƒi) from said family ((ƒi)i∈{0, 1, . . . , n-1}) is based on a set of rules comprising at least one selection rule.
