Abstract

Limited spectral access motivates radio technologies that are capable of performing multiple tasks simultaneously and efficiently cooperating with existing systems. We develop a joint positioning-communications system for a vehicular ad hoc network that simultaneously synchronizes distributed users, performs carrier-phase-accurate localization, and enables network communications. In this paper, we focus on two-way ranging methods for jointly estimating propagation delay and clock offset between the participating nodes in the network. We propose a family of novel one-shot methods to achieve distributed coherence and demonstrate that, for given conditions, such estimators reduce to a system of linear equations, hence, optimal. Here, we study the precision and computational complexity of two of these estimators using simulated flight paths and discuss their region of applicability.
