Patent ID: 11924016

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: encoding (S51) the data sub-streams with respective polar codes, such as to produce m polar-encoded data sub-streams, modulating (S52) the m polar-encoded data sub-streams onto symbols of a multilevel modulation comprising m levels defining 2m different symbols, such as to produce a symbol stream, transmitting (S53) the symbol stream to the receiving device (40), wherein the 2m 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)<1.7m×(0.0425×m−0.06), expression in which:
