Initial code exchange for asynchronous TR-UWB ad hoc networks

Abstract

In this paper, we present an initial code exchange scheme for a transmit-reference ultra wideband (TR-UWB) system. We exploit the facts that a TR-UWB transceiver scheme allows for simultaneous transmission and reception as well as detection and separation of distinct users with the same code even if their data pockets overlap. We exploit the fact that the transmission of UWB pulses is a low power operation compared to the processing needed at the receiver side to make the initial code exchange highly energy efficient.
