Abstract:
1. A data transmitting apparatus in wireless communication system, comprising: an encoder for performing channel encoding on the data; a modulator for modulating the channel-encoded data and outputting a modulated symbol; a pilot inserter for inserting a pilot signal and a first cyclic prefix code in the modulated symbol, wherein the first cyclic prefix code is inserted in the modulated symbol after the pilot signal is inserted in the modulated symbol, and is inserted in the modulated symbol by using at least a portion of the pilot signal inserted in the modulated symbol; a discrete fourier transform (DFT) processor for receiving the modulated symbol in which the pilot signal and the first cyclic prefix code are inserted, and performing an DFT process on the received modulated symbol; a mapping processor for mapping the output of the DFT processor to sub-carriers of an inverse DFT (IDFT) processor; the IDFT processor for performing an IDFT process on the output of the DFT processor; and a cyclic prefix inserter for inserting a second cyclic prefix code in the output of the IDFT processor.
