Wideband and interference-resilient mixed mode time transfer for distributed radios
Abstract
Time synchronization in a network of distributed wireless radios facilitates a range of important applications including ultra-wideband and low latency communication for cognitive radios. Toward this goal, software only techniques are limited by the backend processing speed and their inherent latency. To overcome this, we propose a hybrid hardware/software approach that enables an energy efficient technique for time transfer with substantial improvement in time accuracy compared to exiting methods. The objective of this work is to develop an integrated platform for such precision time transfer across multiple wireless commw1ication nodes. The Pl designs and implements an integrated system that provides scalable operational bandwidth while maintaining interference resiliency for dynamic environments. The proposed work includes several breakout prototypes for testing the high frequency circuit components and system modules. The final phase of the work showcases a hardware/software platform for energy efficient multi-node precision time synchronization for a wideband ad-hoc communication network.
