Abstract:
Transmitting apparatus and receiving apparatus for communication systems using coded orthogonal frequency-division multiplexed (COFDM) dual-subcarrier modulation (DCM) signals. The same coded data is mapped both to COFDM subcarriers located in the lower-frequency half spectrum of the DCM signal and to COFDM subcarriers located in its upper-frequency half spectrum. The mapping of COFDM subcarriers in those half spectra employ labeling diversity preferred for reception of DCM with less error when accompanied by interfering additive white Gaussian noise (AWGN). In preferred forms of COFDM DCM signal, the quadrature amplitude modulation (QAM) of COFDM subcarriers is Gray mapped to position palindromic lattice-point labels along one of the diagonals of each square QAM constellation.

Claim (Index 16):
The  claim 18  transmitter apparatus, wherein said first QAM mapper and second QAM mapper are respectively configured such that:\n (a) said first and second mapping patterns are respective superposition coded modulation (SCM) mapping patterns of similar size, \n (b) the bits more likely to experience error in the labeling of said first set of QAM symbols in accordance with said first SCM mapping pattern correspond to the bits less likely to experience error in the labeling of said second set of QAM symbols in accordance with said second SCM mapping pattern, and \n (c) the bits more likely to experience error in the labeling of said second set of QAM symbols in accordance with said second SCM mapping pattern correspond to the bits less likely to experience error in the labeling of said first set of QAM symbols in accordance with said first SCM mapping pattern.
