Abstract:
1. A method for receiving a signal, named a received signal, corresponding to a data signal sent out by a transmitter to a receiver through a transmission channel, said transmitter comprising N T transmit antennas and said receiver comprising N R receive antennas, with N T and N R being greater than or equal to 2, wherein the method comprises the following steps: analyzing said received signal, delivering a piece of information representing said transmission channel; determining periodically and/or as a function of a variation of said transmission channel: transmitting to said transmitter a parameterizing signal defining said at least one distribution and said specific rates; wherein, in the determining step, an optimized ordered distribution Γ*, the specific rates per group R* for this distribution, and an optimized set S* of the active antennas are determined from the following equations: with: where: H represents said transmission channel; ρ corresponds to signal-to-noise-ratio; {P J Δ corresponds to a group included in the distribution Γ; A
