A method of transmitting data using cyclic delay in a multi-antenna system using a plurality of subcarriers is disclosed. Data is transmitted through a phase shift based precoding scheme enhanced from a related art phase shift diversity and a related art precoding scheme. A generalized cyclic delay diversity scheme is selectively applied to a phase shift based precoding scheme or a related art precoding scheme executed on a frequency domain is transferred to a time domain to be applied as a generalized cyclic delay diversity scheme. Accordingly, complexity of a receiver is reduced and communication efficiency can be enhanced.
