Abstract

The present disclosure relates to a method (50) for transmitting a data stream from a transmitting device (30) to a receiving device (40), the data stream comprising m data sub-streams, said method (50) comprising:- (S51) encoding the data sub-streams with respective polar codes, such as to produce m polar-encoded data sub-streams,- (S52) modulating the m polar-encoded data sub-streams onto symbols of a multilevel modulation comprising m levels defining 2^m different symbols, such as to produce a symbol stream,- (S53) transmitting the symbol stream to the receiving device (40), wherein the 2^m symbols of the multilevel modulation are distributed in the complex plane such that they are regularly spaced along the real axis and the complex axis by a spacing factor K, the predetermined labeling function Z being such that Φ(Z) < 1.7^m × (0.0425 × m - 0.06), expression in which: ΦZ=∑i=1m∑c1,…,cm∑ciʹ,…,cmʹ\ci,…,cme−4K2Zc1,…,cm−Zc1,…,ci−1,cʹi,…,cʹm2
