Abstract
A probabilistic signal point shaping device comprises circuitry configured to map data blocks of input bits of an input bit stream onto mapping symbols, wherein said mapping symbols are distributed according to a predetermined probability distribution and represented by complex-valued signal points or non-uniformly spaced amplitude levels, assign bit labels to said mapping symbols, determine redundancy bits from the bits of said bit labels, transform said redundancy bits into a redundancy rule, and apply the redundancy rule to the mapping symbols to obtain output symbols.
