Method and corresponding transmitter for predistorting a wideband radio signal to avoid clipping

摘要

The invention relates notably to 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.;According to the invention, the method consists in subtracting from the wideband signal filtered pulses in phase the said wideband signal, each filtered pulse corresponding to an overshot, the amplitude of each filtered pulse being dependant on the amplitude of the corresponding overshot and on the predefined threshold.
