<p>PURPOSE: A reference signal transmission method for improving the overall performance of a wireless communications system for an uplink transmission is provided to improve the efficiency of the up link transfer by supporting an uplink transmission using multi transmission antenna. CONSTITUTION: A transmitter(200) comprises next. A data processor(210) processes an information bit. The data processor generates one or more data stream. A precoder(220) performs precoding operation about data stream. A signal generator(230) generates time domain signals in which multiple transmission antennas are put through.</p> |
