ABSTRACT:
A preamble design method of generating a preamble for a plurality of symbols using time waveform data of a specific symbol in an OFDM communication system includes a dividing step of dividing the time waveform data of the specific symbol into a plurality of blocks equivalent to number of symbols in the preamble, a symbol-unit-block selecting step of selecting a separate block from among divided blocks in units of symbols in the preamble, and a symbol-unit time-waveform-data generating step of generating time waveform data having a different pattern for each of the symbols by generating time waveform data for a single symbol in which a selected block is set as a leading block and data are cyclically arranged from leading data in the selected block.
