Abstract

Recently, ultra-wideband impulse radio (UWB-IR) has attracted considerable attention in short-range communications because it offers small-size, low power consumption and gigabit data transmission. Rake reception should be necessary to attain the required E_b/N₀ because of the limited transmit power emission, but it will be unacceptable for the terminal. Therefore, the use of time-reversal UWB-IR (TiR) scheme at the access-point side has been suggested as a promising solution to achieve Rake diversity combining. The TiR is expected to be used in multi-cell channel, but the inter-cell interference (ICI) has not investigated. In this paper, the ICI of TiR is experimentally investigated and compared with a conventional UWB-IR. Ray-Tracing based computer simulation also is done to show good agreement with experiment. As a result, the effect of ICI is found to be suppressed by using the TiR scheme.
