摘要：By considering the three dimensional (3D) antenna arrays and 3D arbitrary trajectories of a mobile station (MS), a generic non-stationary geometry-based stochastic model (GBSM) for multiple-input multiple-output (MIMO) channels is proposed. Under 3D non-isotropic Von Mises Fisher (VMF) scattering scenarios, the theoretical and approximate expressions of time-variant spatial correlation function (SCF) are also derived and analyzed. Simulation results show that the SCFs of proposed model match well with the ones of existing models for the special cases of 1D linear and 2D curve trajectories. In addition, the derived theoretical SCFs also have good agreements with simulated and measured results. IEEE
