Abstract:
A plurality of candidate transmission signals which are modulated according to a discrete Fourier transform (DFT)-spread filter-bank multi-carrier (FBMC)/offset quadrature amplitude modulation (OQAM) scheme and are capable of achieving a single carrier effect are generated. A candidate transmission signal having the smallest peak to average power ratio (PAPR) is selected and transmitted, so that a PAPR performance can be effectively improved.

Claim (Index 6):
The modulation apparatus of  claim 2 , wherein the modulator generates the candidate transmission signals by performing: a first modulation process in which IDFT is performed on the real part symbols multiplied by the phase shift coefficient or real part symbols obtained by inversing signs of odd index symbols after multiplying the phase shift coefficient and then filtering is performed using a poly phase network; a second modulation process in which IDFT is performed on the imaginary part symbols multiplied by the phase shift coefficient or imaginary part symbols obtained by inversing signs of odd index symbols after multiplying the phase shift coefficient and then filtering is performed using a poly phase network; and a third modulation process in which one of an output of the first modulation process and an output of the second modulation process is delayed by T/2, where T denotes a symbol duration of the data symbol, and the outputs are summed up,\n wherein the modulator generates two candidate transmission signals through a first switching operation for selecting the real part symbols multiplied by the phase shift coefficient and the imaginary part symbols multiplied by the phase shift coefficient as an IDFT input of the first modulation process and an IDFT input of the second modulation process, respectively, or selecting the real part symbols with the sign-inversed odd index symbols and the imaginary part symbols with the sign-inversed odd index symbols as the IDFT input of the first modulation process and the IDFT input of the second modulation process, respectively.
