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.
