A low complexity UWB PHY baseband transceiver for IEEE 802.15.6 WBAN

Dealing with critical health issues requires the existence of an intelligent health care system capable of monitoring the patients wherever they are, which increases the demand for a wireless health care system. One possible realization of such a system is the wireless body area network standard defined by IEEE 802.15.6. Based on IEEE 802.15.6, this paper proposes a low complexity implementation of the ultra-wideband physical layer transceiver. A full practical transceiver is introduced with Pulse Shaping, Pulse Deshaping, Time Hopping, Packet Detection and Frame Synchronization included. Chirp pulse is used to shape the data bits in order to minimize the out-of-band radiations. New hardware efficient strategy is used for packet detection. The functionality of the transceiver is tested through computer simulations. All of the design modules were written in Matlab then prototyped using verilog hardware description language. The transceiver is then synthesized targeting 65 nm CMOS technology. The transceiver consumes 443.83 μW in 65 nm technology and conforms to all of standard requirements.
