A twin-cluster MIMO channel model

The paper presents a new approach to geometry-based stochastic channel models that can be used for simulating MIMO systems. We use twin-clusters to represent multiply reflected or diffracted multipath components. The location of the two twins can be chosen independently, in order to correctly reflect DoAs, DoDs, and delays. The model is thus more accurate than existing single-scatterer approaches. Simulation results, using a publicly available version of our model, show a very realistic behavior of our model.
