A 3D RS-GBSM with Uniform Planar Antenna Array for Massive MIMO V2V Channels

In this chapter, a novel three-dimensional (3D) non-stationary vehicle-to-vehicle (V2V) regular-shaped geometry-based stochastic model (RS-GBSM) with uniform planar antenna arrays (UPAs) for massive multiple-input multiple-output (MIMO) communication systems is proposed. A novel method, the so-called BD process and seed-algorithm-based selective cluster evolution, is developed to capture the space non-stationarity. The time non-stationarity is further mimicked by employing this novel method over the entire timeline. In addition, the proposed RS-GBSM divides clusters into static and dynamic clusters to investigate the impact of vehicular traffic density (VTD) on channel statistics. Important statistical properties are derived. Simulation results show that the space-time non-stationarity is mimicked. Finally, an excellent agreement between simulation results and measurements is achieved.
