Abstract :
A general aim of geometry-based stochastic channel models (GSCMs) is provision of imaginary, but realistic propagation channel responses that can be used as a reference channel in evaluating performance of mobile communication systems. This paper provides an overview of recent development in the GSCMs with particular emphases of 1) structural refinement, 2) parametrization, and 3) validation of the model. The refinement in this paper refers to a multi-link extension of the existing GSCM in the form of ”add-on” such that it fits into various implementation of single-link GSCMs. The model parametrization is a tedious but essential work that guarantees the realistic-ness of the GSCM outputs. Finally, it is also crucial to show validity of the GSCM with specific sets of model parameters such that the GSCM outputs show the intended reality of actual propagation channels. Finally, an example of applying the multi-link extension ”add-on” to the COST273 channel model, being one of the improvements led to to the COST2100 channel model, is given.
