中文摘要：

采用多天线技术的60GHz无线通信被认为是未来室内场景下高数据率宽带无线接入一种有前途的解决方案。参考802．11ad工作小组采用的60GHz信道模型，根据60CHz路径损耗公式提出的分布式天线系统间距的优化方案可以保证房间肉功率覆盖的均匀性。在此基础上，进一步分析60GHz多天线系统在不同链路条件下的信道条件数关系，提出一种基于信道条件数的天线选择策略。该策略利用信道条件数判断信道性能，既保证了通信质量，又适时降低系统总功率，切换简单、易于操作，适用于60CHz室内无线通信。

英文摘要：

60GHz wrreless communication using multi-antenna system is a promising solution for future in-building high data rate access network. In accordance with the 60GHz channel models adoped by IEEE 802. llad Task Group, an optimizing scheme of antenna separation distance is proposed for the balance of power distribution in the room. In addition, based on analysis of the condition numbers under different channel state, a condition number-based antenna selection strategy is proposed. As a threshold-handover strategy, it considers both transmit power and BER performance. Easy operation makes it suitable for 60GHzln-building wireless communication.
