Patent ID: 8488718

Claim:
A method of processing a signal in an emission chain for receiving a digital input signal and for providing the signal to be emitted; the digital input signal being decomposed into a plurality of digital delay components having a plurality of pathway-induced delays, including at least a first digital delay component having a first pathway-induced delay to generate a first digital delay signal and a second digital delay component having a second pathway-induced delay to generate a second digital delay signal, said method comprising the following steps: (a) delaying the digital input signal by a third digital delay component to generate a third digital delay signal, the third digital delay signal having a value greater than or equal to the maximum value of each of the first and second digital delay signals; (b) applying a correction delay to each of the first and second digital delay components, including applying a first correction delay to the first digital delay component to obtain the first digital delay signal and a second correction delay to the second digital delay component to obtain the second digital delay signal, the first correction delay and the second correction delay being derived from a comparison between the third digital delay signal and the signal to be emitted; and (c) obtaining the signal to be emitted from a power amplifier by converting the first and second digital delay signals into first and second analog signals, respectively, modulating the second analog signal to generate a phase modulated signal, and inputting the first analog signal and the phase modulated signal to the power amplifier.
