Abstract (en)
[origin: WO2009087329A1] The invention relates to a method for the pre-equalisation of a data signal transmitted by an origin communication entity (EC1) comprising a set of origin antennas (A1 1,...Al M1), to a destination communication entity (EC2) comprising a set of destination antennas (A21,...A2M2), wherein the method comprises a reception step by a reference antenna (A1ref) from the set of origin antennas of a first pulse transmitted by a destination antenna (A2j) on a first propagation channel, a reception step by the reference antenna of a combined pulse response representative of a consecutive crossing of a second pulse on a second propagation channel between an origin antenna (A1i) and the destination antenna and of the first propagation channel, the step of time-returning the combined pulse response, the step of combining the time-returned combined pulse response and a pulse response representative of the crossing of said first pulse on said first propagation channel, the steps being repeated for at least a portion of the set of destination antennas and at least a portion of the set of origin antennas, and the step of determining the pre-equalisation coefficients of the data signal from a set of combinations of pulse responses.
