Abstract:

By considering the 3-D antenna arrays and 3-D arbitrary trajectories of a mobile station, a generic non-stationary geometry-based stochastic model for multiple-input multiple-output channels is proposed. Under 3-D non-isotropic von Mises-Fisher 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 1-D linear and 2-D curve trajectories. In addition, the derived theoretical SCFs also have good agreements with simulated and measured results.
