Abstract
A method (C) for converting a data signal (U), comprising (i) providing an input symbol stream (B) representative of the data signal (U), (ii) demultiplexing (DMX) the input symbol stream (B) to consecutively decompose the input symbol stream (B) into a number m of decomposed partial symbol streams (B_, . . . , B_m), (iii) applying on each of the decomposed partial symbol streams (B_, . . . , B_m) an assigned distribution matching process (DM_, . . . , DM_m), thereby generating and outputting for each decomposed partial symbol stream (B_, . . . , B_m) a respective pre-sequence (bn_, . . . , bn_m) or n_j symbols as an intermediate output symbol sequence, and (iv) supplying the pre-sequences (bn_, . . . , bn_m) to at least one symbol mapping process (BM) to generate and output a signal representative for a final output symbol sequence (S) as a converted data signal. Each of the distribution matching processes (DM_, . . . , DM_m) and the symbol mapping process (BM) are based on a respective assigned alphabet (ADM_, . . . , ADM_m; ABM) of symbols, and the cardinality of each of the alphabets (ADM_, . . . , ADM_m) of the distribution matching processes (DM_, . . . , DM_m) is lower than the cardinality of the alphabet (ABM) of the symbol mapping process (BM).
