Method for communication between an emitter and a receiver, corresponding emitter, receiver and computer program

A communication method implemented in a transmission system comprising an emitter and a receiver, characterized in that the emitter implements:

• receiving at least one piece of information originating from the receiver and enabling the emitter to determine a pre-coding matrix taking account of a covariance matrix of the interference, representative of the spatial structure of the reception interference, according to a technique for acquiring knowledge of the emission channel selected by the receiver from among a group of techniques comprising a first technique based on a compressed version of the covariance matrix of the interference and at least one second technique.

A receiver of a transmission system also comprising an emitter, the receiver comprising means for estimating a covariance matrix of the interference, representative of the spatial structure of the reception interference,

• characterized in that the receiver further comprises:
• means for selecting a technique for acquiring knowledge of the emission channel, in a group of techniques comprising a first technique based on a compressed version of the covariance matrix of the interference and at least one second technique, and
• means for transmitting to the emitter at least one piece of information enabling the emitter to determine a pre-coding matrix taking account of the covariance matrix of the interference according to the technique for acquiring knowledge of the emission channel selected by the receiver.
