A wireless communication method for multi input multi output system and a receiver can be used to reduce the quantization effect in multi input multi output system from the transmitter to the receiver when the transmission using a finite codebook precoding operation. The wireless communication method comprises the following steps: firstly, a downlink channel state information is obtained at a receiver end. Then, at the receiver end, on the basis of the downlink channel state information to select a set of pre encoding matrix labeling a set of pre encoding matrix multiple pre encoding matrix of a finite codebook in one or more pre encoding matrix in the label. After that, the selected pre encoded matrix label and one or more scalar coefficients are transmitted to a transmitter by the receiver. In the transmitter end, according to the pre encoding matrix label and one or more scalar coefficient to produce a refined precoding matrix, and refined using a precoding matrix to between a transmitter and a receiver for data transmission.
