Abstract
A method is provided for transmitting complex data symbols, supplying a multiple carrier signal. The method includes shaping at least one block of M×K complex data symbols, where M>1 and K>1, implementing the following acts: for at least one column of the block, conversion of the M complex data symbols of the column from the frequency domain to the time domain, supplying N converted symbols; cyclic repetition of the N converted symbols, supplying NK repeated symbols; cyclic repetition of the transformed N symbols, supplying NK repeated symbols; filtering the NK repeated symbols via a shaping filter, supplying NK filtered symbols; and summation of the obtained filtered symbols for the various columns of the block, supplying NK time samples.
