An emission chain is suitable for receiving an input signal and for providing a signal to be emitted. It comprises a processing pathway for the input signal which includes a digital signal decomposition according to N signal components, with N an integer greater than or equal to 2, said N signal components, on the one hand, being converted from a digital form into an analog form and, on the other hand, following respectively distinct physical pathways, said physical pathways inducing first respective delays on the N signal components. The input chain comprises a power amplifier. A delayed input signal is obtained by applying a second delay (tau) having a value greater than or equal to the maximum value of the first delays. Next, N correction delays (tau-taui) are applied respectively to the N signal components, this step being carried out on the basis of a comparison between said input signal delayed by the second delay and the signal to be emitted. Finally, the signal to be provided to the power amplifier is obtained by combining the N signal components obtained on completion of the previous step.
