Abstract

The present invention concerns a method for transmitting data to at least one receiver, data being decomposed in a first and a second streams. The method comprises the steps of: - identifying, from a first number of bits of the first stream, a cluster of constellation points among clusters of constellation points of an amplitude phase shift keying constellation, each cluster of constellation points being comprised in a respective circle sector of a first type, each circle sector of the first type being spaced from another circle sector of the first type by a circle sector of a second type, all circle sectors having the same central point, - identifying, from a second number of bits of the second stream, one constellation point out of the constellation points comprised in the identified cluster, - mapping the bits used for identifying to the identified constellation point of the identified cluster of constellation points, in order to form a symbol to be transmitted, - transmitting the symbol to the at least one receiver.
