An Energy-Efficient OFDM-Based Baseband Transceiver Design for Ubiquitous Healthcare Monitoring Applications
Wireless Body Area Network (WBAN) is an emerging technology which is specifically designed for the applications of body signal gathering and monitoring to provide reliable physical information. A typical WBAN consists of multiple of Wireless Sensor Nodes (WSNs) and Central Processing Node (CPN). The CPN is integrated in a portable device, and the WSNs are placed on the human body as tiny patches. These WSNs are capable of sensing, processing, and storing the body signals. Then the information can be transmitted wirelessly to CPN for further processing or other applications.
