A method is provided for detecting, using a mobile apparatus, the central frequency of at least one carrier of a wide-band downlink of a communication channel associated with a frequency band, wherein the at least one carrier belongs to the frequency band. The method includes a first step of measuring the value of an indicator representative of a power received by the mobile apparatus for a plurality of frequencies evenly spaced in the frequency band in order to obtain a spectrum of values of the indicator on the frequency band. The method includes a second phase of analyzing the spectrum of the indicator, which includes recognizing the shape of the at least one carrier in the indicator spectrum, and detecting the central frequency of the at least one carrier.
