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 20):
The modulation method of  claim 18 , wherein the generating of the plurality of different transmission candidate signal sets comprises:\n generating real part Alamouti-coded symbol pairs and imaginary part Alamouti-coded symbol pairs for each of the first antenna and the second antenna the first real part symbol group, the second real part symbol group, the first imaginary part symbol group and the second imaginary part symbol group; mapping the real part Alamouti-coded symbol pairs and the imaginary part Alamouti-coded symbol pairs for each of the first antenna and the second antenna to subcarriers for each of the first antenna and the second antenna in a frequency reversal manner; and generating the transmission candidate signal for the first antenna by modulating the real part Alamouti-coded symbol pairs and the imaginary part Alamouti-coded symbol pairs for the first antenna, which are mapped to the subcarriers for the first antenna in the FBMC/OQAM manner, and generating the transmission candidate signal for the second antenna by modulating the real part Alamouti-coded symbol pairs and the imaginary part Alamouti-coded symbol pairs for the second antenna, which are mapped to the subcarriers for the second antenna in the FBMC/OQAM manner.
