Abstract
The present invention relates to a wireless communication system, wireless communication method and a wireless communication device. In the SVD-MIMO transmission using a singular value decomposition, the feedback from the receiver to the transmitter the amount of information is reduced. The receiver is not sent back to the transmitter weighting vector V, which is the vector V by the receiver channel information matrix obtained by singular value decomposition, but sends the reference symbols to the transmitter, the transmitter is obtained from the channel information matrix and when a singular value decomposition to produce the necessary transmission data vector V. In the process of obtaining the vector V, opposite to the inconsistency between the direction of the channel matrix obtained by calibrating compensation, the calibration can compensate for the error between the transmitter and the receiver transmit and receive both the analog parts.
