Abstract

A modified simulation of ultra-wideband (UWB) multipath channels, combined with cluster classification and physics-based pulse distortion mechanisms, is proposed in this letter. Spatiotemporal characteristics of multipath clusters are specifically generated based on 3 times 3 planar array systems with regard to scenario types and are simulated over ten frequency subbands (2-11 GHz). Thus, frequency-dependent characteristics of the propagation channels are also investigated and compared between each scenario. Finally, the probability of the bit-error rate is determined to quantify distortion effects on UWB multipath channels for all frequency subbands.
