Theoretical Analysis and Sensitivity Modeling of an Energy Detector for IR-UWB Applications

Abstract

This paper deals with the theoretical and behavioral modeling of a IR-UWB front-end system, using MATLAB and ADS PTOLEMY simulators. The main objective of this paper is to make a comparative trial of the sensitivity of an integrator based energy detector and a low pass filter based energy detector. We demonstrated that the use of an integrator for the energy detector improve the sensitivity when several pulses are used in one symbol whereas a filter performs better for unique pulse signaling.
