Abstract:
1. A method of transmitting data in a multi-antenna system, the method comprising: transmitting one or more pilot signals within a first symbol region through a first antenna unit; transmitting one or more pilot signals within a second symbol region through a second antenna unit; puncturing data of a prescribed number among the data within the first symbol region and the second symbol region; and adding a transmission power corresponding to the punctured data to transmission powers corresponding to the pilot signals; wherein a prescribed number of data within the first symbol region is transmitted through the second antenna unit, wherein a prescribed number of data within the second symbol region is transmitted through the first antenna unit; wherein, the prescribed number of data within the first symbol region or the second symbol region is half of a sum of a number of the one or more pilot signals and a number of the prescribed number of punctured data for the corresponding first symbol region or second symbol region; wherein, the transmission powers corresponding to the one or more pilot signals transmitted through the first and second antenna units are set higher than the transmission power corresponding to the punctured data by 1.5 times.
