摘要

The invention relates to a method for a transmitter using at least two transmit antennas to send a multicarrier signal to at least one receiver using at least one receive antenna, comprising a step of obtaining an estimation of at least one downlink transmission channel. According to the invention, such a method comprises a transmission phase implementing at least one iteration of the following steps for at least one downlink channel: sending of useful data over said downlink channel, taking account of said estimation of the downlink channel; updating of said estimation of the downlink channel by taking account of information acknowledging receipt of said useful data, said information being sent by the receiver associated with said downlink channel.
