Abstract (en)
[origin: WO2007057558A1] This method for carrying out the flexible demodulation of data modulated following an amplitude modulation in quadrature is used in a communications system employing a code division multiple access technique (CDMA) and an optical frequency division multiplexing (OFDM) using non-binary spread codes. The invention comprises steps (340) consisting of determining a simplified expression specific to the logarithm of the likelihood ratio.
