1. A method for reducing a Peak to Average Power Ratio (PAPR) of a signal, the signal comprising a plurality of tones, the plurality of tones apportioned into a set of data tones and a set of reserved tones, the method comprising the steps of:

  • modifying a signal value of at least one of the reserved tones according to a first processing method;

    after the modification of the signal value of the at least one of the reserved tones, modifying a signal value of at least one of the data tones according to a second processing method to provide a modified signal; and

    transmitting the modified signal to a receiver.
