Abstract

Abstract:

A new pulse shape based on wavelet for ultra-wideband (UWB) system was presented. The sub-nanosecond pulse, which, referred to as monocycle, was defined as wavelet monocycle because it could be made by selecting the translation and dilation factors of wavelet to meet the FCC spectral mask for UWB system. The performance of time hopping pulse position modulation (THPPM) UWB system using this wavelet monocycle was studied under additive white Gaussian noise (AWGN) channel. The simulation results show that the performance of the UWB system using wavelet monocycle is better than that of other conventional UWB system such as using Gaussian monocycle and Scholtzs monocycle.
