Method of obtaining a transmission gain function by means of an array of antennae, a signal to be transmitted by the array being weighted by a vector ({overscore (b<SUB>d</SUB>) of N complex coefficients, referred to as the transmission weighting vector, N being the number of antennae in the array, the array transmitting to a telecommunication terminal over a transmission channel, referred to as the downlink channel, a downlink transmission signal (S<SUB>d</SUB>) and the said terminal transmitting to the said array over a transmission channel, referred to as the uplink channel, an uplink transmission signal (S<SUB>u</SUB>), the said downlink channel being disturbed by an isotropic noise (N') and/or a directional noise, referred to as the downlink interference (I<SUB>d</SUB>), the said transmission weighting vector ({overscore (b<SUB>d</SUB>) being determined by means of a matrix product from a noise power matrix (D<SUB>d</SUB>) which is a function of the power of the said isotropic noise and/or of the power of the said directional noise and a vector ({overscore (C<SUB>d</SUB>)}), referred to as the downlink channel vector, representing an angular sampling of the transfer function of the downlink channel in M directions k, k=0, . . . , M-1, belonging to the angular range covered by the array.
