ABSTRACT:
A method and apparatus are provided for coding an OFDM/OQAM-type multi-carrier signal formed by a temporal succession of symbols comprising a set of data elements. Each of the data elements modulates a carrier frequency of the signal. Each of the data elements is formed by adding two real values in quadrature, which each correspond to a binary word of a source signal, which is modulated using a pre-determined modulation constellation, such as to transmit information over a real channel and an imaginary channel of the OFDM/OQAM symbols.
