ABSTRACT:
A DCM demapper and a DCM demapping method are provided. The DCM demapper includes: a basic signal generation unit generating a plurality of basic signals using a signal and channel information of two subcarriers; a soft decision generation unit generating a plurality of soft decisions using the plurality of basic signals; and a soft decision selection unit selecting a soft decision corresponding to each bit of the two subcarriers among the generated soft decisions.
