    • A system and a method for performing precoding in a wireless communication system are provided to enable a precoder to perform the precoding of a data stream according to whether spatial multiplexing or transmit diversity is used in a wireless network and enable a code book selection unit to select a code book suitable for each communication session, thereby providing improved precoding. A BS(Base Station)(102) includes a plurality of code books(270) and a code book selection unit(275). The code books include plural composite precoding matrixes generated on the basis of each of corresponding diversity precoding matrixes. The code book selection unit operates to select one of the code books so as to be used in a communication session with a subscriber station. A precoder selection unit(280) is operated to select one of the composite precoding matrixes from the selected code book so as to be used in the communication session with the subscriber station.

    • An apparatus and a method for transmit diversity and beamforming in a wireless network are provided to implement adaptive periodical delay diversity without a loss of performance in a state that antennas and channels are associated with each other. A method for transmit diversity and beamforming in a wireless network comprises the following steps of: receiving a feedback message from a subscriber station in a BS(Base Station)(305); determining whether the correlation of antenna/channel is strong or weak from the feedback information in the BS(310); selecting a transmit diversity scheme for downlink transmission to the subscriber station in the BS when the correlation of antenna/channel for the subscriber station is weak(315); transmitting a downlink signal according to the selected transmit diversity scheme(320); selecting a beamforming scheme for the downlink transmission to the subscriber station in the BS when the correlation of antenna/channel for the subscriber station is strong(325); and transmitting the downlink signal according to the selected beamforming scheme(330).
    • 在无线网络中提供用于发射分集和波束成形的装置和方法,以在天线和信道相互关联的状态下实现自适应周期性延迟分集而不损失性能。 一种用于无线网络中的发射分集和波束成形的方法包括以下步骤:从BS(基站)(305)中的用户台接收反馈消息; 确定天线/信道的相关性是否在BS(310)中的反馈信息中强或弱; 当用户站的天线/信道的相关性较弱时,选择用于BS中的用户站的下行链路传输的发射分集方案(315); 根据所选择的发射分集方案(320)发送下行链路信号; 当用户站的天线/信道的相关性强时,选择用于在BS中的用户站的下行链路传输的波束成形方案(325); 以及根据所选择的波束成形方案(330)发送所述下行链路信号。
