Correction method and correction loop for a complex digital signal

The invention relates to the correction of the delay between the phase and the envelope of a digital signal. In particular, it concerns the application of this correction in digital broadcast transmitters. The present invention offers an alternative solution wherein the use of the original signal is not necessary. No temporal comparison with the original signal is required. An object of the invention is a method for correcting at least one parameter to be corrected pc of the envelope of a digital signal comprising the steps of: - decomposing the digital signal into an envelope signal and a signal phase - determining the correction to apply to the setting of the envelope by searching the minimum of noise powers-band signal.
