Abstract
An orthogonal frequency division multiplexing (OFDM) system and a method of controlling preamble power of the OFDM system are provided. The method includes detecting a present preamble power of a certain base station among a plurality of base stations and a preamble influence factor of the certain base station; detecting a preamble influence factor of at least one neighboring base station of the certain base station; and determining a new preamble power of the certain base station based on at least one among the present preamble power, the preamble influence factor of the certain base station, and the preamble influence factor of the at least one neighboring base station.
