Abstract :
An enhanced multi-antenna channel model is presented, based on the concept of propagation graphs. It employs propagation mechanisms such as reflection, diffraction or scattering in a physically meaningful manner, while it can also be used as a semi-deterministic channel model with randomly distributed scatterers. It is an extension of a recently proposed graph-theoretic channel model by considering realistic scattering coefficients and antenna mutual coupling and can efficiently serve as an evaluation tool for the design of capacity-optimized MIMO antennas and millimeter-wave communication links.
