Ultra-wide bandwidth timing networks
S. Niranjayan, Andreas F. Molisch · 2012
We present an algorithm for ultra-precise timing in large wireless networks. Our approach uses physical-layer UWB round-trip time-of-flight measurements to achieve precise timing between any two nodes, and fast re-timing based on UWB pulse broadcasting and diversity combining, allowing the precise timing to “propagate” through even large-scale networks. The algorithm also ensures that a virtual timing network evolves from a large set of randomly placed nodes. Simulation results show that the algorithm converges and maintains network timing, regardless of the size of the network.
