Abstract:
1. A method for transmitting and receiving data in a multiple-input multiple-output (MIMO) communication system including a transmission apparatus having a plurality of transmission antennas for communicating with a reception apparatus having a plurality of reception antennas, the method comprising: receiving, by the transmission apparatus from the reception apparatus, singular value decomposition (SVD)-decomposed channel information for a channel established between the transmission apparatus and the reception apparatus; performing, by the transmission apparatus, QR decomposition on the received SVD-decomposed channel information; setting, by the transmission apparatus, multiple transmission antennas from among the plurality of transmission antennas, to be allocated to the channel, according to a result of the QR decomposition; and transmitting, by the transmission apparatus, data using the set multiple transmission antennas, wherein the SVD-decomposed channel information is from an effective multiple-input single-output (MISO) channel matrix F
