Zusammenfassung:	PURPOSE: A space time coding OFDM(Orthogonal Frequency Division Multiplexing) based low complexity multiple antenna relay transmitting method is provided to increase diversity gain by using a relay mode, an antenna selection mode, or a circulation delay diversity mode. CONSTITUTION: A signal transmitted to a first timeslot from a source node(100) is received by a multiple receiving antenna. An amplification gain is determined in consideration of average transmission power of each receiving signal. An LC-STBC(Linear Combining-Space-Time Block Coding) signal processing of each receiving signal is performed. The processed signal is amplified as the amplifying gain. The amplified signal is transmitted to a target node(300) through multiple transmission antenna. [Reference numerals] (100) Source node; (300) Target node
