摘要
在对M IMO系统的性能分析中,需要建立精确的M IMO信道模型。基于系统所在的不同环境或不同的应用目的,目前存在多种M IMO信道模型和不同的分类方式。以生成方式是否具有物理意义为标准对现有的信道模型进行了分类,介绍了其不同的应用领域,并且选取其中有代表性的模型,给出了他们在同一环境下生成信道矩阵的容量曲线与特征值分布的比较。
Among the key technologies used in the next generation wireless communications, Multi -Input and Multi -Output technology has drawn considerable attentions in recent years due to its excellent performance on improving the capacity linearly and high spectrum efficiency. In order to analyze the performance of MIMO systems, an accurate MIMO channel model is required. There are many different MIMO channel models now,focusing on different aspects of the realistic channel. In this paper we classify these channels into two categories, one model of each category is selected out, respectively, and singular value distribution, MIMO channel capacity and singular value compare under different correlation conditions are completed.
