点击翻译按钮获取中文摘要

Body area network (BAN) has been considered for specific applications such as medicine, healthcare, firefighter, and military, as well as entertainment applications. This project aimed at solving the fundamental problems of analysis and modeling of dynamic behavior of BAN channel due to the human body motion, by improving the channel sounding systems, simulation approach, and practical modeling, as well as at identifying the highly reliable transmission schemes under the dynamic channels. Major outcomes of the project are summarized into the following four items: (1) Establishment of dynamic multipoint channel sounders, (2) establishment of dynamic BAN channel simulators, (3) antenna de-embedding from BAN channel, and (4) highly reliable transmission schemes for multisensor BAN.
