1. A method for synchronizing a terminal with a frequency from among an ordered initial sequence of frequencies of a radio-communications network, the terminal having available a power spectrum associating to each frequency of the initial sequence a power value representing the power with which the frequency is received by the terminal, wherein the method comprises:

  • determining at least one first range of consecutive frequencies within the initial sequence, associated with a part of the power spectrum that presents a power variation below a first predetermined threshold;

    attempting at least one first synchronization of the terminal with a frequency of said at least one first range;

    in the event of failure of each of said at least one first synchronization, obtaining a modified sequence by modifying a position of the frequency or frequencies of said at least one first range of the initial sequence or by eliminating said at least one first range of the initial sequence; and

    attempting a second synchronization of the terminal with at least one of the frequencies of the modified sequence.
