Abstract:
1. A method for transmitting data in a wireless communication system, the method comprising: determining, by a wireless device, a subcarrier and a subcarrier group to which a data sequence is allocated; modulating, by the wireless device, the data sequence by a transmit filter to generate a data stream, a waveform of the transmit filter determined based on the subcarrier and the subcarrier group; generating, by the wireless device, a transmission signal based on the data stream; and transmitting, by the wireless device, the transmission signal through the subcarrier, wherein the transmission signal is cyclostationary, wherein the data sequence is a sth data sequence allocated to a nth subcarrier group, and the waveform of the transmit filter s where, L is a natural number determined based on a bandwidth of the wireless communication system and a cycle period of the transmission signal, α and f l is a parameter defined by a following equation, where, └ ┘ is a floor function, or where, L is a natural number determined based on a bandwidth of the wireless communication system and a cycle period of the transmission signal, α
