Abstract
In a data transmission method, said data are organized in blocks of K frames, each of said frames being composed of N binary words, each of these binary words being associated with an 'elementary symbol'. Each of the M=K·N elementary symbols per block modulates a different sub-carrier amongst a series of sub-carriers forming an OFDM modulation, the allocation of each elementary symbol to a given sub-carrier being effected so that, when the OFDM signal is demodulated after it is received, a chosen subset is extracted from amongst said K frames. Application to the transmission of data representing compressed images in accordance with the JPEG2000 standard.
