WBAN信道的路径损耗模型

Path loss model for WBAN channel

随着人们对医疗健康的重视,对于无线人体局域网(WBAN)的研究显的越来越重要。然而信道特征的考察是构建网络结构的一个重要组成部分,要构建无线人体局域网网络系统,首先必须了解人体信道模型,拥有完整的信道模型是评价系统性能的基础。本文从不同频点研究无线人体局域网的信道特性,并提出四种通信链路从路径损耗模型和冲激响应模型来具体分析。

Wireless Body Area Network （WBAN） is of importance for telemedicine and tele-health services, so cause attractiveness by engineers. Investigation of the BAN channel plays a very significant role because the wireless channel will determine the communication system. This paper from the different frequency point research of wireless local area network body of channel characteristics, and puts forward four kinds of communication link from the path loss model and impulse response model to specific analysis.
