Abstract

The invention relates to a method for transmitting a group of Q symbols (A0; . . . ; AQ−1) in a DFTsOFDM radio signal, said radio signal being provided by applying a M size DFT and a N-size IDFT to a block of symbols X=(X0, . . . XM−1), said method comprising: —determining Q positions ni in the block of symbols, such as (I); —transmitting the Q symbols through the radio signal, such as for each i, samples of the symbol ai in the radio signal are equal to a result of the application of a DFTsOFDM scheme to a block of M symbols with values of symbols Xni+mL, being ej2πk(ni+mL)/MAi with k integer such as 0≤k<K, with m integer such as 0≤m<K.
