Abstract
The present invention is related to a method for reducing a peak to average power ratio (PAPR) of a signal in a wireless communication system. PAPR is reduced by modulating a data stream into a plurality of symbols, dividing the plurality of symbols into symbol groups, applying a Fourier transform to each of the symbol groups, applying a delay to at least one of the transformed symbol groups, and calculating a peak to average power ratio of the symbol groups.
