Abstract
In a method for encoding at least two data streams (p1 . . . pn), a bit sequence of each one of the at least two data streams (p1 . . . pn) is mapped onto a symbol in a predefined order which is part of one of at least two subsets (I, II, Ia, Ib, IIa, IIb) of a modulation constellation. The one of at least two subset (I, II, Ia, Ib, IIa, IIb) is determined by an encoding rule that is having regard to the symbols (s1 . . . s16) that already have been used for encoding bit sequences of preceding data streams (p1 . . . pn)

Method for encoding at least two data streams (p1 . . . pn) by mapping a bit sequence of each one of the at least two data streams (p1 . . . pn) in a predefined order onto a symbol which is part of one of at least two subsets (I, II, Ia, Ib, IIa, IIb) of a modulation constellation in which the one of at least two subset (I, II, Ia, Ib, IIa, IIb) is determined by an encoding rule that is having regard to the symbols (s1 . . . s16) that already have been used for encoding bit sequences of preceding data streams (p1 . . . pn).
