Analyzing the Power Spectral of Orthogonal Pulse-Based TH-UWB Signals | Chapter 1 | Novel Research Aspects in Mathematical and Computer Science Vol. 8

 This paper investigates the power spectral density (PSD) of orthogonal pulse-based signals for time-hopping ultra wideband (TH-UWB) systems. Our detailed investigation reveals that the PSD of these signals is influenced by the energy spectral density (ESD) of orthogonal pulses as well as the time dithering code and modulation methods. Different order orthogonal pulses change the structure of the continuous spectral component with symbols by producing varying ESD. We show that orthogonal pulse-based signals reduce the dynamic range of amplitude of discrete spectral components. Additionally, we minimise the dynamic range by applying longer TH code over orthogonal pulse-based signals. As a result, average transmitted power boosts performance of the UWB system. The PSD of a TH-UWB signal based on orthogonal pulses is given a detailed theoretical analysis, and it is backed up by simulation results.
