Parametric MIMO model for ray tracing/launching simulations

A parametric model (PM) that reconstructs the MIMO (multiple-input multiple-output) channel from a single SISO (single-input single-output) realization using a ray launching/tracing engine is presented in this work. This model uses spherical propagation and image theory. The novelty of this model is that it takes into account variations in the diffraction coefficient. It is shown that spherical propagation and variations in the diffraction coefficients must be taken into account in short-range distances.
