| 摘 要： | 提出一种发射分集结合空间复用的MIMO通信方法——分组分集复用法(GDM)。发射机将发射天线分组，每组采用全空间分集发射相同的数据流，发射机根据反馈信道反馈的接收信噪比调整分组大小。与传统的发射分集或空间复用相比，提出的方法可以根据不同的信道灵活地分配用于分集和复用的天线，使系统能够适应不同的业务质量或信道的瞬时变化。

| Abstract: | A new MIMO system is presented in this paper. Transmitting antennas are divided into groups and independent streams of data are transmitted from each group using full space diversity. The group size can be adjusted based on SNR received from feedback channels. Compared with traditional diversity and multiplexing, the provided scheme can assign transmitting antennas flexibly based on channel state information. Consequently, the MIMO system can adapt itself to the changes of service quality and channels. |
