Energy-quality system design for in-body communication.
With the explosive development of wireless communication technology, more and more implanted medical devices appear in everyday life. Because of the limited energy resource in implanted devices, the energy-quality wireless system design is the biggest challenge. In this paper, we update our former system level energy model and make it suitable for implantable medical communication system. In the new model, the impacts of human body tissue on the signal transmission are considered. The wireless system energy consumption is minimized by adjusting the digital base-band and RF parameters such as signal bandwidth, peak-to-average ratio (PAR), modulation levels, data rates etc. In the communication quality evaluation, we consider the effects of 1/f noise and the third-order harmonic distortion in addition to normal channel noise.
