Method of issuance by a base station equipped with an antenna several sensors to a mobile

According to this method of transmitting a digital signal by a base station equipped with an antenna to a plurality of sensors to a mobile in the presence of interference sources and background noise is calculated at least one frequency transposition operator which transforms approximately a reception calibration table into a calibration table transmission or reception; calculating statistical data from the signals received by the different sensors from the mobile and the interference sources; is calculated for mobile, an optimum set of spatial weightings from statistical data, the frequency transposition operator and capacity criterion of the useful signal and reducing the interference; is weighted digital signal from the optimal set of weights and then emits.
