Patent ID: 7817733

Claim:
A method for peak limiting suitable for use in a communication system, comprising: modulating a symbol vector to produce a modulated waveform, wherein the symbol vector contains at least one symbol in at least one subcarrier; computing at least one symbol adjustment that is based on at least one peak overshoot of the modulated waveform; and applying the at least one symbol adjustment to the symbol vector in accordance with an assigned weighting for reducing a peak power of the modulated waveform, wherein the applying is an iterative process that repeats the method steps of modulating, computing, and applying the at least one symbol adjustment for limiting a distortion energy in the at least one subcarrier to a prespecified level; assigning at least one weight to the at least one symbol adjustment, wherein the at least one weight corresponds to the prespecified level of distortion in the at least one subcarrier; and wherein different predetermined weights are assigned to data symbol subcarriers, pilot symbol subcarriers, idle subcarriers, out-of-band subcarriers, and reserved subcarriers.
