COMMUNICATION METHOD USING A PREAMBLE TO SHARE CHARACTERISTIC INFORMATION, METHOD FOR GENERATING THE PREAMBLE, AND COMMUNICATION SYSTEM TO WHICH THE METHODS ARE APPLIED

摘要

A communication method for a transmitter using a preamble in a wireless communication system comprises the steps of: determining two or more subcarriers from among a plurality of subcarriers for the preamble; mapping a subcarrier sequence of the preamble and a subcarrier phase value to the two or more subcarriers; and transmitting the preamble using the two or more subcarriers. Here, the preamble comprises a mistake element including a first repetitive pattern, and an imaginary element including a second repetitive pattern, which are within a preset time period of a time domain; and the relationship between the first repetitive pattern and the second repetitive pattern shows the characteristic information of the wireless communication system.
