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.
