ABSTRACT:
A diversity circuit uses a plurality of sub-carriers showing CINRs below a lowest threshold, so as to form a sub-carrier group so that combined CINR of the sub-carriers is above the lowest threshold. A diversity tone map generator generates a tope map associated with the lowest primary modulation scheme, based on output from the diversity circuit. A tone map generator generates a tone map associated with primary modulation schemes applied to respective sub-carriers, based on output from the diversity tone map generator.
