摘要：
A method is provided for selecting a precoding matrix to be used in an MIMO communication system. The MIMO communication system includes a transmitter, a receiver and a communication channel. The precoding matrix is used by the transmitter to precode codewords to be transmitted to the receiver over the communication channel. At the receiver, an optimum precoding matrix within a codebook of precoding matrices is determined based on a metric related to the power of received signal layers. An indication is then fed back from the receiver to the transmitter to enable the transmitter to select the optimum precoding matrix from the codebook.
