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 11):
The  claim 9  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 square QAM mapping patterns of similar size, and \n (b) none of the map labels in said first and said second mapping patterns that is palindromic is in a similar outside corner of both said first and second mapping patterns.
