空間通道模型系統層級模擬之探討

Introduction to Spatial Channel Model for System-level Simulation

摘要


MIMO技術在目前的通訊標準發展中扮演著重要的角色,而如何提供一個模擬多天線通訊的通道模型即為一重要議題,有鑑於此,3GPP/3GPP2制定出空間通道模型SCM,考慮了角度延展、延遲延展、多路徑干擾的功率、延遲以及路徑方向等等的影響因素,更提供了三種主要的模擬環境以及數個可供選擇的模擬選項,本文將針對SCM主要的模擬流程與計算方式加以說明。

MIMO plays an important role in the development of the communication specification at present time. How to provide a channel model to simulate communication of multiple antennas is an important issue. Hence, 3GPP/3GPP2 specify the parameters and methods of the spatial channel model with the consideration of angle spread, delay spread, power, delay, and direction of multipath. SCM provides three primary simulation environments and several optional scenarios. In this paper, we introduce the simulation procedures and calculation methods of the primary simulation environments of SCM.
