Abstract: A method of a transmitting node may comprise: modulating a codeword corresponding to data to be transmitted; generating sparse space-frequency block code (SSFBC)-coded symbols by encoding the modulated codeword in an SSFBC scheme; performing precoding on the SSFBC-coded symbols for each of subbands respectively corresponding to transmit antenna groups; and transmit the precoded SSFBC-coded symbols by performing beamforming on the precoded SSFBC-coded symbols using at least one array antenna group among two or more array antenna groups.
