Abstract
A method is provided for receiving a signal, corresponding to a data signal transmitted by a transmitter to a receiver via a transmission channel. The method includes the following steps: analyzing the signal received, delivering an information item representative of the transmission channel; determining, periodically and/or as a function of a variation of the transmission channel: at least one distribution of the transmission antennas into at least one group of at least one antenna as a function of the information item representative of the transmission channel, wherein at least one group includes at least two transmission antennas for at least one of the determinations; and specific efficiencies assigned respectively to each of the groups of antennas for each distribution as a function of the information item, and transmitting to the transmitter a parameterization signal defining the at least one distribution and the specific efficiencies.
