Design and implementation of a body monitoring baseband system for human body communication

Wireless body area network (WBAN) brings great convenience in the field of medical monitoring. This paper presents a new design and implementation of baseband system for human body monitoring. The system consists of a configurable node digital baseband subsystem and a hub digital baseband subsystem. In order to enable the system more efficient and flexible, We propose an optimized communication protocol on the basis of IEEE802.15.6 and design a new network management unit (NMU) for the hub which is similar with the lookup table. The baseband system is verified on the FPGA prototype platform with 2-Mb/s system data rate. With the SMIC 0.13μm technology, the area and power of node digital basband are 183985μm² and 1.6634 mW, and the cost of hub are 160703μm² and 1.6918 mW.
