Abstract: A method for reducing the quantization effect of precoding operations utilizing a finite codebook in multiple-input multiple-output (MIMO) or multiple-input single-output (MISO) systems from a transmitter to a receiver is provided. First, downlink channel state information is obtained at the receiver side. A set of indices of precoding matrices or a set of precoding matrices within the finite codebook are determined according to the obtained downlink channel state information at the receiver side. The selected indices of precoding matrices and a set of scalar coefficients are transmitted from the receiver to the transmitter. Thereafter, a refined precoding matrix is generated based on the set of indices of precoding matrices and the one or more scalar coefficients at the transmitter side. The refined precoding matrix is applied for transmission between the transmitter and the receiver.
