Provided in the present invention is an OFDM received signal processing method comprising steps of: generating information on at least one channel by using at least one preamble signal transmitted from a transmitter; eliminating a first interference signal from the received signal transmitted from the transmitter by using the channel information; eliminating a second interference signal from the received signal where the first interference signal is eliminated by using the channel information; and demodulating the received signal where the second interference signal is eliminated. When the second interference signal is eliminated, cyclicity components are eliminated from the received signal where the first interference signal is eliminated. [Reference numerals] (S510) Generate information on a channel via a channel estimation; (S520) Eliminate an ISI signal by using the information on the channel; (S530) Process channel equalization; (S540) Eliminate an ICI signal by using the information on the channel; (S550) Correct an error via a hard decision; (S560) Restore a delay path power; (S570) Decode a received signal where an interference component is eliminated |
