US 2013/0155831 A1 · METHOD AND APPARATUS FOR DETECTING RADIO SIGNAL

Abstract

In an aspect, a method for transmitting data in a wireless communication system is provided. A wireless device determines a subcarrier and a subcarrier group to which a data sequence is allocated. The wireless device modulates the data sequence by a transmit filter to generate a data stream. A waveform of the transmit filter is determined based on the subcarrier and the subcarrier group. The wireless device generates a transmission signal based on the data stream. The wireless device transmits the transmission signal through the subcarrier. The transmission signal is cyclostationary.
