超宽带 (UWB) 通信是生物医学体域网 (BAN) 中一项很有前景的技术。本文研究了胸部可穿戴式 BAN 链路和植入式 BAN 链路的性能，分别对应于胸部到腰部和胸部从内到外的通信链路。通道模型首先基于频率相关时域有限差分（FDTD）方法和逼真形状的人体模型导出，重点关注身体姿势的统计变化。然后获得这两条链路的 RAKE 接收器的误码率 (BER)。
Ultra wideband (UWB) communication is a promising technique for biomedical body area networks (BAN). In this paper, the performance of wearable and implant BAN links on chest, which correspond to communication links of chest-to-waist and chest inside-to-outside respectively, are investigated. The channel models are first derived based on the frequency-dependent finite difference time domain (FDTD) method and a realistic-shaped human body model with an emphasis on the statistical variations of body postures. Then the bit error rates (BER) for a RAKE receiver are obtained for these two links.
