Timing Acquisition for Code-Orthogonalized Transmitted-Reference Ultra-Wideband (UWB) Wireless Communication System

Abstract

The code-orthogonalized transmitted-reference (COTR) impulse-based ultra-wideband wireless communication system has been recently proposed based on the standard transmitted-reference (TR) and frequency-shifted reference (FSR) impulse-based ultra-wideband system by the authors. This paper studies timing acquisition for the COTR-UWB system. The mathematical expressions of synchronization output function in additive white Gaussian noise and multi-path fading environments are deduced first, followed by a simulation on the synchronization algorithm. The outcome of simulation demonstrates that the COTR-UWB system is capable of quick and simple synchronization, without sacrificing the complexity of the receiver.
