Title: DISTRIBUTING COHERENT SIGNALS TO LARGE ELECTRICAL DISTANCES OVER SERIAL INTERCONNECTIONS
Abstract:
A method involving a serial interconnection system having a first node, a second node, a plurality of calibration nodes that are electrically connected in series by the serial interconnection system, and a plurality of connection nodes corresponding to the plurality of serially connected calibration nodes and electrically connected in series by the serial interconnection system, the method involving: for each of the plurality of calibration nodes performing a measurement procedure involving: injecting a corresponding reference signal into that calibration node; and while the corresponding reference signal is being injected into that calibration node, determining a summation of the phases of signals appearing at the first and second nodes; from the determined phase summations for the plurality of calibration nodes, computing phase corrections for each of the plurality of calibration nodes; and applying the phase corrections to the corresponding plurality of connection nodes.
