Claim:
1. A method for receiving data in a wireless communication system using transmission diversity, the method comprising: receiving, by a receiver, a signal including precoded data symbols on a plurality of resource blocks, each resource block comprising Orthogonal Frequency Division Multiplexing (OFDM) symbols and one OFDM symbol from among the OFDM symbols comprising a plurality of first resource elements and a plurality of second resource elements; determining, by a resource element demapper, whether the precoded data symbols are mapped to the plurality of first resource elements in the one OFDM symbol; demapping, by the resource element demapper, a precoded data symbol from one resource element from among the plurality of first resource elements of the one OFDM symbol if the precoded data symbol is mapped to the one resource element from among the plurality of first resource elements in the one OFDM symbol; and decoding, by a decoder, the precoded data symbol according to a symbol precoding scheme, wherein at least one resource element from among the plurality of first resource elements in the one OFDM symbol is muted if a separation between two resource elements which are available to assign the at least one pair of precoded data symbols in the one OFDM symbol is three or more subcarrier indices, wherein the at least one muted resource element is located in the one OFDM symbol having the two resource elements, the separation between the two resource elements which are available to assign the at least one pair of precoded data symbols is the three or more subcarrier indices, wherein the demapping of the precoded data symbol is skipped for each resource element that is muted, and wherein reference signals are mapped to the plurality of second resource elements in the one OFDM symbol.
