Abstract
This paper aims to perform a link budget analysis for a typical application in wireless implant body area networks (BANs), i.e., capsule endoscope. Ultra wideband (UWB) technology is an attractive candidate for wireless body area communications, especially for providing a high data rate to fulfill real time transmission. In this study, based on the channel characterization and average bit error rate (BER) evaluation results in pulse position modulation (PPM) or on-off keying modulation impulse radio (IR) UWB system over in-body to on-body communication channel, system margin on both single fading channel and two-branch diversity channel are firstly derived and compared, then the link parameters including the communication distance, data rate as well as required transmit power are discussed to clarify the link budget improvement with adoption of diversity reception technique.
