A method for processing a signal received by a receiver, the received signal being derived from two continuously phase-modulated signals.

Abstract

The invention relates to a method for processing a received signal derived from two continuous phase-modulated signals, comprising the following steps: frequency shifting (102) of the squared received signal so as to produce: a first and a second shifted signal having a spectrum shifted by D / 2 and -D / 2 respectively with respect to a spectrum of the squared signal, where D is a bit rate of each of the two continuous phase-modulated signals; determination (108): of a first and a second frequency at which a power spectral density of the first and second shifted signals takes a first and second maximum value respectively, of a third frequency at which a power spectral density of the squared signal takes a third maximum value; central tendency measurement of the frequencies to estimate (110) a frequency difference between the received signal and each of the two continuous phase-modulated signals.
