Applicability of UWB Double Directional Propagation Modeling for Evaluating UWB Transmission Performance

Ultra WideBand (UWB) technologies have attracted much attention due to their potential to realize high data rate transmission, low-power consumption, and high precision ranging and positioning. In designing and evaluating UWB systems, one must inevitably consider multipath channels. In most UWB transmission simulations, the multipath channels are practically generated by channel models. Here, there are two types of channel models in demand mainly by different purposes: channel models for system design, and channel models for assessing equipment. In the former use, channel models are used to compare performances of transmission schemes, such as modulation and coding, so that one can state the superiority of the proposed approach.
