Abstract(in English) | The Pre-Rake scheme ultra-wideband (UWB) communications system is proposed in a standardized UWB channel model from IEEE802.15 SG3a, which is based on an extensive set of indoor short-range channel measurements in this paper. The Pre-Rake scheme is shown to contribute to the low-power, cost-effective UWB system designing as well as Rake combining gain. Instead of building a Rake receiver in the receiving side (e.g. Portable Unit), the transmitter (e.g. Access Point) can pre-diversity the UWB signal before transmission in the forward link estimating the channel impulse response from the reverse link. While the pre-Raked signal is convolved with the estimated channel impulse response, the function of Rake combining at the receiver is automatically performed. Monte-Carlo simulations are carried out to compare the Pre-Rake with Rake. This result show that Pre-Rake scheme is as good as Rake combining. Then the mobile or portable unit with a conventional receiver can still achieve the diversity gain of Rake combining. |
