Abstract

Disclosed are an apparatus and a method for reducing a peak to average power ratio (PAPR) in a filter bank multicarrier system. A transmission apparatus according to an embodiment of the present invention comprises: a discrete Fourier transform (DFT) unit for generating DFT-spread data symbols by performing an N-point (N is the number of subcarriers) DFT on parallel data symbols; a sign inversion unit for generating first data symbols by applying a first sign inversion rule to the DFT-spread data symbols, and generating second data symbols by applying a second sign inversion rule, which is different from the first sign inversion rule, to the DFT-spread data symbols; a modulation unit for generating a first transmission candidate signal and a second transmission candidate signal by modulating the first data symbols and the second data symbols according to a filter bank multicarrier (FBMC)/offset quadrature amplitude modulation (OQAM) scheme, respectively; and a selection unit for measuring a peak value or a peak to average power ratio (PAPR) of the first transmission candidate signal and the second transmission candidate signal, selecting a transmission signal having the smaller peak value or smaller PAPR among the first transmission candidate signal and the second transmission candidate signal, and transmitting the selected transmission signal.
