Abstract: The present disclosure relates to a data transmission procedure, and in particular, to a modulation method using a class of punctured N-dimensional symbol constellations. To this end, embodiments of the invention proposes a transmitting device, a signal format for the transmitting device, and a method, configured to be adapted for using the N-dimensional symbol constellations. The transmitting device is configured to generate a sequence of symbols by mapping a message onto a punctured N-dimensional symbol constellation, wherein the punctured N-dimensional symbol constellation is a full N-dimensional symbol constellation minus an exclusion set, which is a subset of symbols of the full N-dimensional symbol constellation. The full N-dimensional symbol constellation is a Cartesian product of N identical 1-dimensional symbol constellations.

Abstract: The invention relates to a channel encoder (400) configured to encode an information word u of length K -J bits with K > J > 0 into a code word x of length N bits with N - K = M > 0 , wherein the code word x contains the information word u and M + J parity bits p and wherein the channel encoder (400) is configured to implement a probabilistic shaping scheme for the M + J parity bits p such that the code word x = [u, p] is a code word of a linear code C and the M + J parity bits p fulfil a first shaping constraint.

Abstract: The invention relates to a state-dependent distribution matcher for a channel encoder for encoding data bits or symbols into shaped bits or symbols having a non-uniform distribution. The state-dependent distribution matcher comprises: a first binary distribution matcher configured to generate on the basis of a first subset of a plurality of data bits a first subsequence of shaped bits; and a second binary distribution matcher configured to generate on the basis of a second subset of the plurality of data bits a second subsequence of shaped bits. The state-dependent distribution matcher is configured to generate a sequence of shaped bits on the basis of the first subsequence of shaped bits, on the basis of the second subsequence of shaped bits, and on the basis of a sequence of state bits by selecting (i) a respective shaped bit from the first subsequence, in case a corresponding state bit is equal to 0, or (ii) a respective shaped bit from the second subsequence, in case a corresponding state bit is equal to 1.
