Time-Reversal Based Range Extension Technique for Ultra-wideband (UWB) Sensors and Applications in Tactical Communications and Networking

Abstract

This technical report (quarterly) details the work for Office of Naval Research (ONR) by Tennessee Tech. The goal of this project jointly funded by ONR, NSF, and ARO is to build a general purpose testbed with time reversal capability at the transmitter side. The envisioned application is for UWB sensors and tactical communications in RF harsh environments where multipath is rich and can be exploited through the use of time reversal. The over the-air demonstration of the concept of time reversal for a ultra-wideband radio has been achieved recently in our Lab. In particular, synchronization has been obtained over the air. This even is, indeed, a landmark in the development of UWB radios. Time reversal represents a new transceiver framework that is an alternative to the transceivers using OFDM and RAKE receiver.
