摘要

In this paper, the propagation of ultra-wideband (UWB) pulse based on time reversal (TR) technique is studied by finite-different time-domain method in indoor environment. Time compression and spatial focusing of TR waveform are simulated and the propagation of multi-waveform string is analyzed. Then UWB wireless signal transmission based on TR concept is studied numerically. The studied results indicate that the UWB communication based on TR technique can obtain better Inter-Symbol Interference (ISI) and Co-Channel Interference (CCI) performance than traditional one because of its unique property.
