ABSTRACT:
The invention relates to a multicarrier signal consisting of a temporal succession of symbols formed by a set of data elements, each of said data elements modulating a carrier frequency of said signal, said symbols being organized in successive frames each comprising a plurality of symbols, one of said carrier frequencies modulated, at a given point in time, by one of said data elements being called a carrier.According to the invention, at least some of said frames each comprise at least one reference symbol integrally consisting of reference data elements known at least to one receiver and complying with at least one constraint on the value of at least one of said reference data elements, so as to obtain the reduction, at reception, of at least one interference term affecting at least another of said reference data elements.
