Path-Based Spatial Channel Modeling

White Paper

The Spatial Channel Model (SCM) was designed for evaluating multiple-antenna systems and algorithms. The model was developed within a combined 3GPP/3GPP2 ad hoc group to address the need for a precise channel model able to facilitate fair comparisons of various MIMO proposals. The model uses a system-level approach to simulate performance across the range of conditions expected in a cellular system. This ensures that multiple-antenna algorithms are not only optimized for a few test conditions, but across the system as a whole.

This white paper specifically addresses commonly encountered spatial models used by the wireless industry. Topics that are addressed include:

Path characteristics
Introduction to the spatial channel model (SCM) & spatial channel model-extended (SCME)
Model overview
Correlation between modeled components
Why wideband parameters are correlated
Generating SCM model components
Path characteristics
Tap delay-line model
Winner-II
SCM & SCME in standards
