Providing an introduction to the fundamentals of body area communications, this book covers the key topics of channel modeling, modulation and demodulation, and performance evaluation
A systematic introduction to body area networks (BAN), this book focuses on three major parts: channel modeling, modulation/demodulation communications performance, and electromagnetic compatibility considerations. The content is logically structured to lead readers from an introductory level through to in-depth and more advanced topics.
* Provides a concise introduction to this emerging topic based on classroom-tested materials
* Details the latest IEEE 802.15.6 standard activities
* Moves from very basic physics, to useful mathematic models, and then to practical considerations
* Covers not only EM physics and communications, but also biological applications
* Topics approached include: link budget, bit error rate performance, RAKE and diversity reception; SAR analysis for human safety evaluation; and modeling of electromagnetic interference to implanted cardiac pacemakers
* Provides Matlab and Fortran programs for download from the Companion Website

Autoren-Porträt von Jianqing Wang, Qiong Wang
Jianqing Wang, Department of Computer Science and Engineering,Graduate School of Engineering, Nagoya Institute of
Technology, Japan Prof Wang has been working in wireless
communications since 1991, and began bio-medical EMC research in
1995. Since 1997, when he became a full professor, he has engaged
in body area communications for healthcare, medical, and in-car
applications. Prof Wang's considerable experience in both
communication and biology makes him an active member in several
body-area-communication-related academic committees, as well as an
invited speaker at international conferences. He teaches several
related courses to graduate students and has prepared materials for
the class lecture. He holds a PhD and Masters in Engineering
from Tohuku University, and Bachelors in Engineering from Beijing
Institute of Technology.
Qiong Wang, Department of Electrical Engineering and
Information Technology , Dresden University of Technology,
Germany Dr Wang achieved his Phd in Engineering from the
University of Nagoya, Japan, in 2010. Whilst studying he worked at
the same university as a technical assistant and is now based in
Germany at Dresden University of Technology.
