  • Patent number: 7292642
    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.

  • Patent number: 7272188
    Abstract: A multicarrier signal, which includes a temporal succession of symbols formed by a set of data elements, each of said data elements modulating a carrier frequency of the signal. The data elements include reference elements called pilots, whereof the value in transmission is known to at least one receiver designed to receive the signal and informative data elements, whereof the value in transmission is not known a priori to the at least one receiver. One of the caffier frequencies is modulated, at a given time, by one of the data elements, being called a carrier. At least one constraint is imposed on the value of at least one of the informative data elements, so as to reduce, in reception, at least one term of interference affecting at least one of the pilots.

  • Publication number: 20040062191
    Abstract: The invention concerns 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, the data elements comprising reference elements called pilots (20) whereof the value in transmission is known to at least one receiver designed to receive said signal and informative data elements (21-28), whereof the value in transmission is not known a priori to the or said receiver(s), one of said carrier frequencies modulated, at a given time, by one of said data elements, being called carrier. The invention is characterised in that it at least one constraint is imposed on the value of at least one of said informative data elements, so as to reduce, in reception, at least one term of interference affecting at least one of said pilots.
