ABSTRACT:
A method of varying the power output of a transmitter. The method includes providing bit-loading information associated with each tone of multiple tones, where the multiple tones include a first set of tones. The method also includes producing, for transmission, on the first set of tones a first set of constellation symbols based upon the bit-loading information. The method also includes producing a second set of constellation symbols for transmission, where there is a difference of n bits between the bit size of the second bit sequence constellation symbol on each tone of the second set of tones and the bit-loading information associated with each tone of the first set of tones, and where n is an integer greater than or equal to 0.
