Abstract:
This paper evaluates the impacts of pulse shapes and modulation format on energy and power consumption for wireless body area networks (WBANs) based on ultra wideband (UWB). Microelectronic devices (e.g., sensors, transceivers, etc.) are components of this network, used to monitor biological signal activities in vicinity, over the body or by implants. An impulse radio (IR) is addressed for this purpose using UWB frequencies. The basic waveforms Gaussian pulse derivatives and Prolate Spheroidal wave function (PSWF) are presented to study the tradeoff between time- and frequency-limited signals as a possible solution to increase the energy efficiency. The total energy consumption is measured via simulations, considering the signal characteristics, the WBAN payload, the pulse position modulation (PPM), and on-off keying (OOK) schemes.
