Experimental detection and synchronisation validation for a TR-UWB system based on the time delayed sampling and correletion scheme

Abstract

The detection and synchronization experimental validation of the "Time Delayed Sampling and Correlation" (TDSC) detection scheme for transmitted reference ultra-wideband signals (TR-UWB) is presented. This structure has been proposed to achieve a UWB system with low cost, low complexity and low power consumption for medium to low data rate applications which includes ranging for localization purposes. The scheme is implemented in CMOS technology and a test platform has been designed. Detection of TR-UWB signals and the principle of the proposed synchronization process have been done successfully in both a direct cable connection as well in a wireless system with a real channel. In both cases they were used in the sub GHz band (group 1) and also in the low band UWB signals. Further work and experimental results are also shown for a distance measurement strategy, based on the time of arrival (TOA) using the TDSC scheme. © Springer-Verlag Berlin Heidelberg 2012.
