摘　　要：随着无所不在的医疗保健时代的来临,人体局域网(BAN)受到了国内外研究人员的广泛关注。为了促进人体局域网技术的发展,IEEE 802.15-TG6小组拟定了BAN技术规范草案,该技术规范草案中定义了三个物理层:窄频带、超宽带、人体通信。本文将对BAN窄带物理层发射模型进行研究。BAN基带发射模型包括信道编码、扩频、交织、扰码、调制。根据草案提出的规范,搭建BAN基带发射浮点数模型,并对搭建的模型进行仿真验证。结果表明,在适当的信噪比情况下,搭建的基带发射浮点数模型得到了较理想的误码率,满足了BAN通信技术的要求,为后续BAN物理层研究打下了基础,同时也有利于整个BAN物理层基带的完善。With the advent of the era of ubiquitous healthcare, BAN has been widespread concerned by domestic and abroad researchers. In order to promote the development of BAN technology, IEEE 802.15-TG6 works out a technical specifications draft of BAN, it defines three physical layers： ultra-wideband, narrowband, and human body communication. This paper will study transmission model of narrowband physical layer of BAN. This model includes channel coding, spreading, interleaving, scrambling, modulation. According to the proposed draft specification, build transmission float model of BAN baseband, then simulate and verify the built model. Under appropriate SNR, The result shows that the built model gets ideal BER, meets the requirement of BAN communication technology, lays the foundation for the further research of BAN physical layer, and helps improve the entire BAN baseband physical layer.
