Timing Acquisition and Demodulation of an UWB System Based on the Differential Scheme

Free registration required

Executive Summary

Blind synchronization constitutes a major challenge in realizing highly efficient Ultra Wide Band (UWB) systems because of the short pulse duration which requires a fast synchronization algorithm to accomodate several asynchronous users. In this paper, the authors present a new Code Block Synchronization Algorithm (CBSA) based on a particular code design for a non coherent transmission. Synchronization algorithm is applied directly on received signal to estimate timing offset, without needing any training sequence. Different users can share the available bandwidth by means of different spreading codes with different lengths.
