Abstract:
A transmitting apparatus for modulating data based on a predetermined 2q-QAM constellation and a receiving apparatus and method for demodulating a signal based on the predetermined 2q-QAM constellation, wherein the last q-2 bits corresponding to a quadrant of the predetermined 2q-QAM constellation are same with a gray code of a 2q-2-QAM constellation, the last q-2 bits corresponding to the remaining quadrants of the predetermined 2q-QAM constellation are determined by performing symmetric transformation for the last q-2 bits of the quadrant of the predetermined 2q-QAM around the x-axis or the y-axis.
