Abstract: A smart key authentication method for a vehicle remote key system that includes a smart key performing bi-directional communication with a vehicle to control the vehicle and a vehicle authentication module provided at the vehicle to authenticate the smart key is provided. The smart key authentication method includes generating, by the vehicle authentication module, a random number and sharing the random number with the smart key and performing a first authentication process based on the random number, and performing, by the vehicle authentication module, a second authentication process by comparing at least one location information value among an access point (AP) list, a satellite-based positioning sensor value, or a geomagnetic sensor value, which are respectively measured at the vehicle and at the smart key and determining whether or not to permit an authentication to the smart key.

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.

Abstract: An Alamouti coding method includes mapping real number data symbols to a first subcarrier to an (N/2−1)th subcarrier, based on indices of the subcarriers, mapping the mapped real number data symbols and real number data symbols constituting an Alamouti coded symbol pair to an (N/2+1)th subcarrier to an (N−1)th subcarrier, in a frequency inversion scheme with reference to an (N/2)th subcarrier, adjusting a phase of each real number data symbol mapped to the first subcarrier to the (N/2−1)th subcarrier, by using a first phase adjustment value, based on indices of the mapped subcarriers and an index of a time interval, and adjusting a phase of each real number data symbol mapped to the (N/2+1)th subcarrier to the (N−1)th subcarrier, by using a conjugate value of a first phase adjustment value for a corresponding real number data symbol and the real data symbols constituting the Alamouti coded symbol pair.
