Abstract:
1. Method for estimating the transfer function for a multicarrier signal transmission channel formed by a series of symbols in time composed of a set of data elements, each of the data elements modulating a carrier frequency of the signal, the data elements comprising reference elements for which the transmission value is known to at least one receiver that will receive the signal, and information data elements representing at least one source signal to be transmitted, characterized in that it comprises: and wherein during the determination step, the method uses at least one step for selection of at least some of the discrete prolate spheroidal sequences (DPSSs), as a function of at least one characteristic of the transmission channel; and wherein the selection step uses a sub-step to sort the two-dimensional discrete prolate spheroidal sequences (DPSSs) as a function of a predetermined energy criterion (Q
