Abstract:
A method and apparatus are provided for emitting and receiving a signal in a multi-antennae system, using spatial precoding. A method for emitting a signal from an emitter towards a receiver via a transmission channel, in the form of a set of data flows, includes distributing the emission antennae into a plurality of groups containing at least one antenna, at least one group containing two antennae, according to at least one piece of information representing the transmission channel. The method also includes: attributing an efficiency to each emission antenna; allocating an emission power to each data flow; and spatial precoding the signal, using a matrix for diagonal precoding by blocks, containing at least two blocks, each block being associated with one of the groups of antennae.
