A system and method of transmit diversity for wireless communication. The system includes a transmitting terminal having a plurality of transmission antennas and a receiving terminal having a plurality of receiving antennas. The method includes analyzing channel state information obtained by the transmitting terminal; selecting an antenna to be one in use from the receiving antennas; matching the selected antenna in use with the wireless signals that are to be transmitted; transmitting wireless signals that are matched to the receiving terminal for being calculated and determining the pre-selected antenna in use, thereby significantly reducing complexities of the receiving terminal.
