Abstract:
An emission chain, comprising a processing pathway for an input signal which includes a digital signal decomposition according to N signal components, with N an integer greater than or equal to 2. The N signal components being converted from a digital form into an analog form and following distinct physical pathways that induce first respective delays on the N signal components. A delayed input signal is obtained by applying a second delay (τ) having a value greater than or equal to the maximum value of the first delays. Next, N correction delays (τ−τi) are applied respectively to the N signal components based on a comparison between said input signal delayed by the second delay and the signal to be emitted. Finally, the signal to be provided to a power amplifier is obtained by combining the N signal components obtained on completion of the previous step.
