Abstract

Device comprising processing means (MT), transmission channels (VE1, . . . VEn), an antenna array for transmitting signals comprising a number of antennas (A11 . . . A1n) respectively associated with the transmission channels, a number of digital-analog converters (DAC) and a number of phase-shifting means (MD1, . . . MDn) respectively associated with the antennas, said phase-shifting means (MD1, . . . MDn) being placed between the processing means (MT) and the digital-analog converters (DAC) and including digital all-pass filters of FIR type (PT), the processing means comprising control means (MC) configured to adjust the coefficients and/or the order of the all-pass filters of FIR type.
