使用UWB进行无线短距离，低利率通信由于其低功耗和非常高的带宽而引起了不断增长的兴趣。此外，它能够在少数几厘米的范围内提供准确的本地化。关于这些素质，希望设计一个IR-UWB收发器，该收发器在将电池驱动的无线传感器应用于电池驱动的无线传感器时消耗尽可能少的功率。因此，在本文中研究了基于标准IEEE的IRUWB收发器。802.15.4A，特别着重于能源效率，数据速率，潜伏期，同步和前序检测。本文展示了官方标准IEEE.802.15.4A的优化潜力。研究和合并了不同的优化方法。
Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Moreover, it is able to offer accurate localization in the range of few centimeters. Regarding these qualities, it is desirable to design an IR-UWB transceiver which consumes as little power as possible when it is applied for battery driven wireless sensors. For this reason an IRUWB transceiver based on the standard IEEE.802.15.4a was investigated in this paper with particular emphasis on energy efficiency, data rate, latency, synchronization and preamble detection. This paper demonstrates the optimization potential of the official standard IEEE.802.15.4a. Different methods for optimization are investigated and combined.
