【摘要】 随着通信技术的发展,高速的近距离超宽带无线体域网受到越来越多的重视。该文采用基于频域的无线信道测量平台,对3～5GHz频率范围的人体范围无线宽带信道进行测量,其中测量环境分为办公室和静室环境,人体模型包括3种不同体型;获得的测量数据通过统计建模,得到了路径损耗模型和功率群延迟模型。对标准模型与本文模型的仿真结果进行比较表明:该模型在平均附加时延、均方根时延扩展、峰值20dB内多径数目等方面更加符合实测数据。更多还原

【Abstract】 With the development of communication technology,high-speed short-range ultra-wide band wireless body area networks have received increasing attention.This paper used frequency domain-based wireless channel measurement platform to measure three types of human body channel in both the office and anechoic environments within the 3-5 GHz frequency.The statistical analyses gave a wireless channel model with the path loss and power delay profile.Simulations show that this model is more accurate than the standard models for the mean excess delay spread,the root-mean-square(RMS) delay spread,and the number of multi-paths in the 20 dB ranges.更多还原
