Abstract

The invention relates to a method (C) for converting a data signal (U) comprising the steps of: (i) providing an input symbol stream (IB) of input symbols (IBj) representing converted base data signal (U), and (ii) applying a distribution matching process (DM) to a continuous sequence of partial input symbols (IBj) covering k consecutive input symbols (IBj) of said input symbol stream (IB) k ), to generate and output a final stream of output symbols (OB) or a preform thereof of successive output symbols (OBj), wherein said k is - but not necessarily a fixed - natural number, wherein said distribution matching process (DM ) is based on and / or includes multiple (n) distribution matching functions (f i ) family ((f i ) i∈{0,1,...,n‑1} ), the execution of the distribution matching process (DM) is performed by selecting from the family ((f i ) i∈{0,1,...,n‑1} ) of the distribution matching function (f i ) acts on the partial input symbol sequence (IB k ) to achieve, and where, from the family ((f i ) i∈{0,1,...,n‑1} ) to choose a distribution matching function (f i ) is based on and / or controlled by a set of rules comprising at least one selection rule.

Description

technical field [0001] The invention relates to a method for converting or reconverting a data signal, as well as a method and a system for data transmission and / or data reception. Background technique [0002] From the field of converting, transmitting and / or receiving data signals over certain types of channels in order to communicate sequences of symbols, a certain degree of power consumption is accompanied by underlying processes which should be kept as low as possible. Furthermore, difficulties arise in the case of high data loads under streaming conditions. [0003] and "Block-toblock distribution matching" published by Amjad in 2013 and "Algorithms for simulation of discrete memory-less sources" published by Amjad in 2013 sources"), both describe variable-fixed-length distribution matchers selected in a predetermined and fixed manner. Contents of the invention [0004] It is an object of the present invention to provide a method of converting or reconverting a d...
