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. In the past quarter, we focused on rethinking about the role of the radio test-bed and on preparing for improving the test-bed. Bit rate scalability is preferred for reliable transmission in different channel conditions. To transmit over a longer distance, current bit rate of 6.35 Mb/s is too high.
