| Abstract: | The characteristic of indoor UWB wireless channel is studied by using time-domain ray tracing method based on both propagation characteristic of electromagnetic wave and feature of UWB systems.Using time-domain ray tracing method not only derived parameters of indoor wireless channel such as delay spread which overcome the complex problem of frequency-domain ray tracing method, but contributed to designing and analyzing of practical UWB system. |
