Patent ID: 8243833

Claim:
Method for transmission of a multicarrier signal formed by a temporal succession of symbols comprising a set of data elements, each of said data elements modulating a carrier frequency of said signal, said data elements comprising firstly reference data elements called pilots, a value at transmission of at least certain of said pilots being known to at least one receiver designed to carry out a reception of this signal and secondly informative data elements, a value at transmission of said informative data elements being not known a priori to said receiver or receivers, one of said carrier frequencies modulated at a given instant by one of said data elements being called a carrier, wherein the method comprises: a step of computation of an interference affecting a set of at least two data elements to be protected, said data elements to be protected being spaced out two by two from at most one carrier in time and at most one carrier in frequency, said interference taking account of the value of said data elements to be protected and of the values of the data elements of a contour ring constituted by said carriers that are immediately adjacent to said data elements to be protected; and a step of determining at least one value to be assigned to at least one data element of said contour ring, to reduce said computed interference at reception.
