PURPOSE: A method and an apparatus for deriving an accurate estimation value from prediction data in a closed loop transmission diversity mode are provided to accurately estimate transmission patterns in a wireless communication system while being operated in the closed loop transmission diversity mode. CONSTITUTION: The prediction of a future state of a channel from common pilot channel signals transmitted from a base station transceiver(12) is formed at a mobile transceiver(14) to control future transmission patterns of the base station transceiver(12) at a specified time. The matching accuracy of the future transmission patterns to the channel is improved by adaptively calculating channel prediction terms from past and present channel estimation values. Using the channel prediction terms, a wireless communication system(10) with the base station transceiver(12) having antennas operated in a closed loop transmit diversity mode, and a channel controller application(24) at the mobile transceiver(14) select the best antenna transmission characteristics for active antennas of the base station transceiver(12).
