Patent ID: 8050340

Claim:
A method of interleaving symbols that are to be allocated to carriers of a multicarrier transmitter device comprising a module for multiplexing and modulation by N FFT orthogonal functions, the transmitter device implementing a set of carriers made up of data carriers and null carriers, wherein the method comprises the steps of: selecting in time-varying manner, from the set of carriers, a subset of N pm carriers dedicated to conveying data symbols, as a function of an estimate of a transfer function of a transmission channel for a transmitted signal corresponding to the modulated orthogonal symbols generated from data symbols by the module for multiplexing and modulation; and inserting n 0 null carriers within the preceding selection at positions that are determined as a function of the estimate of a transfer function in order to form a block of N′ pm carriers dedicated to transmitting a symbol block, wherein N′ pm =N pm +n 0 ≦N FFT .
