Peak-to-average power ratio (PAPR), fractional bandwidth and processing gain of UWB schemes

This paper addresses the peak-to-average power ratio (PAPR), fractional bandwidth and processing gain of ultra-wideband (UWB) signals. First, the PAPR of UWB signals are derived and the numerical examples demonstrating PAPR values with Gaussian monocycle pulse shaping are presented. We then examine the FCC order authorizing the use of UWB signals and demonstrate that the FCC order presents a broader definition of UWB signals as compared to the original DARPA definition. Finally, we determine the processing gain for FCC compatible UWB signals subject to various data rates.
