A method is provided for receiving a multicarrier signal including a time-based succession of symbols, each including a plurality of multicarriers bearing data, at least one of said symbols including at least one reference pilot. The method includes the following steps: a first estimation of a propagation channel, in accordance with a first estimating technique taking into account the or said reference pilots; at least one second estimation of said propagation channel, in accordance with a second estimating technique different from said first technique; comparing said first and second estimations, delivering an error signal; detecting at least one interfering signal in said propagation channel, by analyzing said error signal.
