Abstract
There are provided an apparatus and a method for reducing a peak to average power ratio (PAPR) through the recombination of an orthogonal frequency division multiplexing (OFDM) symbol. The apparatus includes an orthogonal frequency division multiplexing (OFDM) symbol transforming unit, a peak power measuring unit, and an OFDM symbol selecting unit, wherein the OFDM symbol transforming unit generates the plurality of OFDM symbols by (a) performing a process of rotating the OFDM symbol by a predetermined angle in a complex plane and performing cyclical shifting with respect to the rotated OFDM symbol and (b) repetitively performing process (a) with respect to the cyclically shifted OFDM symbol. Therefore, diversity is secured, whereby the PAPR may be reduced.
