Abstract:
1. Process for transmitting a multicarrier signal comprising a temporal succession of symbols formed by a set of data elements, each of said data elements modulating a carrier frequency of said multicarrier signal, said data elements comprising firstly reference elements called pilots, for which the value at emission is known to at least one receiver that will receive said signal, and secondly informative data elements for which the value at emission is not known to said receiver in advance, one of said carrier frequencies modulated, at a given point in time, by one of said data elements being called a carrier, characterised in that, for at least one of said pilots, the transmitting process comprises the following steps: determining a set of carriers close to said pilot in time-frequency space and being each modulated by one of said informative data elements; imposing at least one constraint on the value of at least one of said informative data elements modulating carriers from the set of carriers, as a function of the other informative data elements modulating carriers from the set of carries, in order to reduce at reception at least one interference term affecting said pilot.
