20100091896 | SIGNAL TRANSMISSION SYSTEM USING MULTIPLE ANTENNA AND SIGNAL TRANSMISSION METHOD THEREOF - The present invention relates to a multiple antenna transmission system and a signal transmission method In the signal transmission method using multiple antennas, a plurality of subcarrier symbols are grouped as a plurality of groups including first and second tiles that are basic resource management units including two or more subcarriers included in a set frequency domain, phases of subcarrier symbols included in a first tile are shifted to be a first phase shifting value, and phases of subcarrier symbols included in a second tile are shifted to be a second phase shifting value that is different from the first phase shifting value. | 2010-04-15 |
