| 摘 要： | 多天线技术有多种实现模式,不同的实现模式有不同的特点和应用场景。文章首先介绍了波束赋形(BF)、循环延迟分集(CDD)、空间分集(SD)、空间复用(SM)等各种多天线技术实现模式的原理。进而分析了各种多天线模式的技术特征以及他们适合的应用场景。基于这些分析,文章提出了一种多天线模式自适应切换算法,他能根据应用场景或者无线信道特征,自适应地选择最优的多天线模式来发送数据,从而进一步发挥多天线技术的优势。

| Abstract: | Multi-antenna technology can be implemented in several modes,and different modes have different characteristics and are used in different scenarios. This paper introduces beamforming（BF）, Cyclic Delay Diversity（CDD）, Space Diversity（SD）, Spatial Multiplexing（SM）, and other multimode antenna technologies. It also analyses various technical features and their application scenarios. A self-adaptive multi-antenna switching algorithm is proposed that is capable of choosing a suitable mode for sending data according to the scenario or wireless channel conditions. This switching algorithm improves multi-antenna technology and enhances the quality of wireless network communications. |
