BER Simulations of a UWB Spatial Multiplexing System Using an Extended Ray-Tracing Approach

This letter investigates the performance of a previously published hybrid channel model, where a standard ray-tracing model is combined with a statistical approach for simulation of dense multipath components. In particular, this hybrid method is compared against measurements and conventional ray-tracing simulations with respect to path loss, delay spread, and bit error rates of a 22 multiple-input-multiple output multiband OFDM (MIMO-MB-OFDM) system. It is seen that the hybrid method outperforms the conventional ray-tracing model, delivering very realistic performance estimates.
