Abstract
A method for clipping a wideband signal in order to eliminate signal overshots having an amplitude above a predefined threshold before submitting the wideband signal to a power amplifier. The method subtracts, from the wideband signal, filtered pulses in phase with the wideband signal, each filtered pulse corresponding to an overshot, and the amplitude of each filtered pulse being dependant on the amplitude of the corresponding overshot and on the predefined threshold. The subtraction step is repeated at least twice on the wideband signal.
