摘要：
An apparatus and method for partial adaptive transmission in a Multiple-Input Multiple-Output (MIMO) system are provided. The method includes estimating a correlation matrix between Transmit (Tx) antennas and an average Signal to Noise Ratio (SNR) and generating a long-term precoding matrix composed of a predetermined number of dominant eigen dimensions of the correlation matrix by using the estimated correlation matrix and average SNR. The apparatus and method provide a new adaptive MIMO transmission method capable of reducing the feedback information overhead and maximizing performance.
