Abstract (en)
[origin: WO2009087328A1] 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 (A11,... A1M1), to a destination communication entity (EC2) comprising a set of destination antennas (A21,...A2M2), wherein the method comprises the step of transmitting (E1) a pulse from a destination antenna (A2j) to the origin communication entity, the step of transmitting (E6) from the destination antenna to the origin communication entity a time-returned combined pulse response representative of a consecutive crossing of said pulse on a first propagation channel between the destination antenna and a reference antenna (A1ref) from the set of origin antennas, and a second propagation channel between an origin antenna (A1i) and the destination antenna, said step being repeated for at least a portion of the set of origin antennas, the pulse transmission steps and the iterative step of transmitting a time-returned combined pulse response being repeated for at least a portion of the set of destination antennas, and the step of determining (E9) the data signal pre-equalisation coefficients from a combination of a set of time-returned combined pulse responses received by the origin communication entity.
