Abstract

In one embodiment, a system is configured to generate a time reference where the system includes a bi-directional loop configured to have a first propagation speed in a first direction and a second propagation speed in a second direction, wherein the first propagation speed is substantially equal to the second propagation speed. In one embodiment, the system further includes a plurality of system elements coupled to the bi-directional loop, wherein each respective system element of the plurality of system elements is configured to determine a time reference common to each as an average arrival time at the respective system element of a first signal transmitted in the first direction over the bi-directional loop and a second signal transmitted in the second direction over the bi-directional loop.
