摘要：
A method is provided for estimating a propagation channel composed of successive symbols of a multicarrier signal, each comprising at least one reference pilot and a plurality of data-carrying frequencies. Such a method comprises, in particular, at least one step consisting of correcting the at least one reference pilot on the basis of a first estimation of a propagation channel, in order to provide a second, more precise estimation of the channel.
