APPARATUS AND METHOD FOR GROUPING ANTENNAS OF Tx IN MIMO SYSTEM WHICH CONSIDERS A SPATIAL MULTIPLEXING AND BEAMFORMING

摘要

The present invention is of the transmitter to a transmission antenna, img id =" 2 "file =" 112010026216293-pat00171.jpg "wi =" 5 "he =" 6 "img-format =" jpg "/ In of a mobile communication system including a receiver having a receive antenna, the transmitter is the the transmit antennas grouped by the img id = "4" file = "112010026216293-pat00173.jpg" wi = "6" he = "6" img-format = "jpg" / method for transmitting the symbols to receive antennas, the one corresponding to the receiving antenna the size of the matrix with the first course and receive feedback from the receiver, the receive antennas in response to the first matrix comprises sub matrixes and performing the eigenvalue decomposition for each of the steps of calculating the sum of the maximum eigenvalue combined the eigenvalue decomposition results for each of the sub-matrix, the maximum of the sum of the maximum eigenvalue for each of the sub-matrix, comprises the step of transmitting different symbols from the respective transmit antennas to a combination of transmission antennas corresponding to the element including the sub-matrix having a value comprising the process and, said transmission antenna group for determining a transmission antenna group.
