摘要

A method is provided for transmitting an information sequence from a source entity to a recipient entity, via at least one relay entity. The method includes: transmitting, by said source entity, modulated symbols representative of said information sequence, obtained after modulation of said information sequence, on a first channel, called ‘source’ modulated symbols; and transmitting, by said at least one relay entity, modulated symbols representative of said information sequence, obtained after modulation of an estimation of said information sequence on a second channel, called ‘relay’ modulated symbols, said first and second channels being orthogonal between each other. The source entity and the at least one relay entity simultaneously send at least one of said ‘source’ modulated symbols and at least one of said ‘relay’ modulated symbols.

1. A transmission method of an information sequence from at least one source entity to a recipient entity, via at least one relay entity, wherein the method comprises:
transmitting, by said at least one source entity, modulated symbols representative of said information sequence, called ‘source’ modulated symbols, each ‘source’ modulated symbol corresponding to a point of a first constellation of order n; transmitting, by said at least one relay entity, modulated symbols representative of an estimation of said information sequence, called ‘relay’ modulated symbols, each ‘relay’ modulated symbol corresponding to a point of a second constellation, of order m. the points of said first and second constellations all being separate, and wherein said at least one source entity and said at least one relay entity simultaneously send at least one of said ‘source’ modulated symbols and at least one of said ‘relay’ modulated symbols.
