Abstract

The present invention relates to an OFDM receiver capable of receiving a single carrier transmission signal to which guard intervals are added, and to a receiving method therefor. More particularly, the present invention relates to an OFDM receiving method capable of receiving a single carrier transmission signal to which guard intervals are added, wherein the OFDM receiving method involves receiving a single carrier transmission signal to which a transmitter adds guard intervals at every predetermined number of signals (hereinafter, "number of sub-carriers" in a receiver) in response to a channel delay longer than a general guard interval, wherein the OFDM receiving method comprises: a step (S100) of taking, as an input through an A/D converter (20), a signal received in an RF block (10) via a receiving antenna; a first receiving step (S200) of receiving the input signal by a first receiver (30); a second receiving step (S300) of receiving the same input signal by a second receiver (40) simultaneously with the first receiving step (S200); and a selecting step (S400) of selecting either the first receiver (30) or the second receiver (40) which has less data errors in an agreed preamble. Thus, the receiving performance of the OFDM receiver can be improved even when a channel delay is shorter or longer than a guard interval. Particularly, the present invention relates to a method for performing data-decoding in response to a channel delay longer than a general guard interval having 1/4 to 1/8 of the length of a data symbol.
