基于几何的随机信道模型（GSCMs）扩展到支持多链路仿真，通过应用公共集群的概念。这种新颖的方法旨在通过调整经由不同链路中的相同簇同时传播的功率的量来控制不同链路之间的相关性，即链路间相关性。基于双链路信道测量，分析了常见簇的行为，并提出了一种基于常见簇的多链路GSCM。此外，基于仿真研究了常见簇对链路间相关性和总速率容量的影响。最后，仿真和测量之间的比较，以表明所提出的多链路GSCM的有效性。
Geometry-based stochastic channel models (GSCMs) are extended to support multi-link simulations by applying the concept of common clusters. This novel approach aims to control the correlation between different links, inter-link correlation, by adjusting the amount of power simultaneously propagating via the same clusters in the different links. The behavior of common clusters is analyzed based on dual-link channel measurements, and a multi-link GSCM is developed based on common clusters. In addition, the effects that the common clusters have on inter-link correlation and on sum rate capacity are investigated based on simulations. Finally, comparison between simulations and measurements is done in order to indicate the validity of the proposed multi-link GSCM.
