Abstract:
An apparatus and method for filter bank multi-carrier signal modulation with a low peak-to-average power ratio (PAPR) in a multiple antenna system are disclosed. According to embodiments of the present disclosure, in a multiple antenna transmission method, after a plurality of transmission candidate signals, which are modulated for each antenna using discrete Fourier transform (DFT) spread filter bank multi-carrier and offset quadrature amplitude modulation (FBMC/OQAM) techniques and are capable of obtaining a single carrier effect, are generated, a transmission candidate signal with a low PAPR can be selected and transmitted, and thus peak-to-average power ratio performance can be effectively improved, and interference between subcarriers can be eliminated by applying an Alamouti coding manner.

Claim (Index 27):
The modulation method of  claim 20 , the generating of the real part Alamouti-coded symbol pairs and the imaginary part Alamouti-coded symbol pairs comprises:\n generating a fourth real part symbol group in which signs of symbols whose index is an odd number among symbols included in the second real part symbol group, and a fourth imaginary part symbol group in which signs of symbols whose index is an odd number among symbols included in the second imaginary part symbol group are inverted; outputting the second real part symbol group and the second imaginary part symbol group or the fourth real part symbol group and the fourth imaginary part symbol group, according to a first switching control bit; generating the real part Alamouti-coded symbol pairs for each of the first antenna and the second antenna by encoding the first real part symbol group and a real part symbol group, which is output according to the first switching control bit, to Alamouti code; and generating the imaginary part Alamouti-coded symbol pairs for each of the first antenna and the second antenna by encoding the first imaginary part symbol group and an imaginary part symbol group, which is output according to the first switching control bit, to Alamouti code.
