Abstract:
1. A preamble design method of generating a preamble for a plurality of symbols using time waveform data of a specific symbol in an orthogonal frequency division multiplexing communication system, the preamble design method comprising: dividing the time waveform data of the specific symbol into a plurality of blocks equivalent to a number of symbols in the preamble; selecting a divided block from among the plurality of blocks; generating each symbol in the preamble by setting a corresponding selected block as the leading block and arranging other blocks of the plurality of blocks cyclically after the leading block; and configuring the preamble by contiguously arranging each symbol generated according to an order in which each selected block was selected, each symbol in the preamble having a different pattern from the other symbols in the preamble.
