Abstract
This application discloses a soft value extraction method and device applicable to an OvXDM system, and the OvXDM system. In the method, waveform coding is performed on all symbols in a hard value sequence, to generate a predictive value after overlapped coding; the symbols in the hard value sequence are reversed one by one, and overlapped coding is performed on each reversed symbol and associated symbols before and after the reversed symbol, to generate a predictive value of the reversed symbol; and for each symbol in the hard value sequence, a soft value of the current symbol is calculated based on A×(−), where A is a coefficient related to a channel type,=∥y−y∥, and=∥y−y∥; if yis a predictive value of the symbol obtained after overlapped coding and before reversing, yis a predictive value of the symbol obtained after overlapped coding and reversing; and yis a received signal sequence.
