Claim:
1. A method of transmitting data, performed by a wireless communication system using transmission diversity, the method comprising: precoding content data into a plurality of data symbols, the precoded data symbols including at least one pair of precoded data symbols; determining the number of first resource elements in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of a resource block, the OFDM symbol including the first resource elements which are available to assign the precoded data symbols and second resource elements; mapping the precoded data symbols to a plurality of resource elements from among the first resource elements of the OFDM symbol; and transmitting the precoded data symbols mapped to the plurality of resource elements from among the first resource elements, wherein, if the number of first resource elements in the OFDM symbol is determined to be an odd number, at least one resource element from among the first resource elements in the OFDM symbol is muted, and wherein reference signals are mapped to the second resource elements in the OFDM symbol.
