APPARATUS AND METHOD FOR TRANSMITTING DATA USING A PLURALITY OF CARRIERS

摘要

The present invention relates to a data transceiving method in a communication system based on a plurality of carriers, and more particularly, to a method of designing a sequence in a communication system using orthogonal subcarriers. The present invention includes the steps of generating a time-domain sequence with a specific length in a time domain, generating a frequency-domain sequence by performing a DFT or FFT operation on the time- domain sequence according to a length of the generated sequence, including a DC subcarrier and a guard subcarrier in the frequency-domain sequence, and performing an IDFT or IFFT operation on the frequency-domain sequence including the DC subcarrier and the guard subcarrier.
