Abstract

Realistic evaluation of a multiple-input multiple-output (MIMO) system in an indoor rectangular corridor is carried out using an image based 3-D ray-tracer. The simulated patterns of the antennas used are incorporated in the simulations. Results show that the channel statistics such as correlation depend strongly on the receiver locations sampled. Using a set of randomly distributed points it is shown that the capacity of a 2×2 system using antennas with low mutual coupling closely follows the performance of an ideal MIMO channel.
