摘要 首先分析超宽带通信的无线传播环境,介绍了目前国内外的研究现状,针对各种室内模型的优缺点,提出采用室内传播统计模型,对室内UWB(超宽带)通信的无线链路进行预测,能够比较精确地反映室内特点,并利用该模型对室内UWB无线信道的容量进行了计算,仿真结果表明室内环境下,在短距离内(<10 m)实现低功率,高速率(超过100 Mbps)是可行的。 In this paper we analyze the radio propagation environments of the ultra-wideband communications, introduce recent advances in these topics and propose to use the statistical path loss model which can match the indoor environments perfectly to evaluate the path loss of the UWB (ultra-wideband) indoor channels. We use this model to calculate the capacity of the UWB indoor channels. The simulation results show that UWB can achieve very high data rates( 100 Mbit/s and above) for short range( 〈 10 m) indoor applications.
