A Study of Differences in Calculated Capacity when using Single-, Mixed- or Multiple-Bounce GSCM schemes

The paper looks for differences in MIMO system capacity when using either single-, mixed-, or multiple bounce geometry based stochastic channel models (GSCMs). The investigation considers Saleh- Valenzuela temporal indoor model, expanded for angular domain. In the model omnidirectional and idealized sector antennas were used as array elements. The single-bounce assumption, combination of single and multiple bounces, and pure random multiple bounces assumption were compared within “temporally identical” environment regarding the overall MIMO capacity. Assumption of clustered scatterers/reflectors is used in all three cases. The comparison is performed in statistical sense, using a large number of stochastically generated temporal models. The model is two- dimensional, i.e. neither elevation angle nor polarization/ depolarization was considered.
