  • Methods and systems for communicating signals through multi-carrier systems
    Publication number: 20070047665
    Abstract: Methods and systems for communicating a signal through a multi carrier system session are disclosed. The carrier channel includes a plurality of subcarriers. A bit value for each subcarrier of the plurality of subcarriers is determined (202, 402) based on the signal to be communicated. The plurality of subcarriers is divided (204, 404) into a first set of subcarriers and a second set of subcarriers based on the bit value for each subcarrier of the plurality of subcarriers. The first set of subcarriers is turned off (206, 406). The second set of subcarriers is then modulated (208, 408).
