Abstract
Provided are a system and method for generating phase-coherent signaling via invocation of a respective phase synchronization calibration factor among wireless communications nodes. The calibration factor substantially and simultaneously removes an effect of multipath interference and propagation phase shift as between the nodes, thus allowing a direct correlation of phase with respect thereto in a subsequent phase-based ranging regime.
