A multi-cluster geometry-based stochastic model for 5G massive MIMO channels in NLOS environment

With the continuous development of the fifth generation (5G) mobile communication systems, Massive MIMO is one of the most promising technologies of the academic and the industry [1]. In order to better assess the system performance, it is essential to build a corresponding channel model accurately. The paper presents a new approach to geometry-based stochastic channel models that can be used for simulating Massive MIMO systems. We use multiple clusters to represent multiply reflected or diffracted multipath components. The position of the multiple clusters is chosen in the appropriate way. Simulation results, using a publicly available version of our model, show a very realistic behavior of our model.
