The present invention relates to a wireless relay communication system and its method. Particularly, the present invention relates to a wireless relay communication system and its method using cyclic precoding. The wireless relay communication system includes a transmitter which transmits a wireless signal; relays which receive a wireless signal transmitted from the transmitter, apply cyclically the code value of a code book calculated in advance, and transmit again the signal after precoding the wireless signal; and a receiver which receives a wireless signal transmitted from the relays. The structure of a receiving terminal is simplified even though the number of the relays is three or more, by precoding a signal received from each relay by using the code and transmitting the signal again. Thereby, a single symbol can be decodable at one time. |
