Systems, methods and circuits are implemented in a various manners. Consistent with one such implementation, a method is employed for use in a system using a dual-carrier modulation (DCM) scheme that uses two quadrature-amplitude modulated (QAM) signals, the first QAM signal having an I1 and Q1 component and the second QAM signal having an I2 and a Q2 component. The method includes receiving the QAM signals (310) and transforming the received QAM signals into an I1-I2 domain or a Q1-Q2 domain (312). A data bit is decoded by calculating a Euclidean distance from constellation points in the I1 to I2 domain (314). The decoded data bit is then stored (316). |
