在本文中，我们考虑了在蜂窝环境中运行的自适应 MIMO SVD（奇异值分解）传输方案的性能。我们特别考虑小区间干扰对自适应 MIMO 系统性能的影响。小区间干扰始终存在于蜂窝系统中。然而，它的值可以由蜂窝布局的类型控制，即扇区的数量和频率复用模式。在本文中，我们考虑了多种蜂窝布局，并考虑了所得 SINR 对可支持的星座大小、BER 等的影响。用于我们性能分析的主要指标是无差错传输速率，这是针对自适应 MIMO SVD 系统推导的。对于所考虑的蜂窝场景，我们发现干扰的影响相当大，并且自适应 MIMO SVD 方案的性能仅比传统分集方法提供的性能稍好一些
In this paper we consider the performance of an adaptive MIMO SVD (singular value decomposition) transmission scheme operating in a cellular environment. In particular we consider the impact of inter-cell interference on the performance of an adaptive MIMO system. Inter-cell interference is always present in a cellular system. However, its value may be controlled by the type of cellular layout, i.e., the number of sectors and the frequency reuse pattern. In this paper we consider a number of cellular layouts and consider the impact of the resulting SINR on the constellation sizes that can be supported, the BER, etc. The primary metric used for our performance analysis is the error free transmission rate, and this is derived for the adaptive MIMO SVD system. For the cellular scenarios considered, we find that the effect of interference is considerable and the performance of the adaptive MIMO SVD scheme is only marginally better than that provided by conventional diversity methods
