METHOD FOR EMITTING AND RECEIVING A SIGNAL IN A MULTI-ANTENNA SYSTEM, USING SPATIAL PRECODING, AND CORRESPONDING EMITTER, RECEIVER, AND COMPUTER PROGRAM PRODUCTS

摘要

The invention relates to a method for emitting and receiving a signal in a multi-antennae system, using spatial precoding, and corresponding emitter, receiver and computer program products. The invention also relates to 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, said method comprising a step of distributing 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 said transmission channel. According to the invention, such a method also comprises: a step of attributing an efficiency to each emission antenna; a step of allocating an emission power to each data flow; and a step of spatial precoding of said signal, using a matrix for diagonal precoding by blocks, comprising at least two blocks, each block being associated with one of the groups of antennae.
