Methods and systems for selecting the shortest path in a multi-path environment

摘要

Methods and systems are described for determining the shortest RF path in a multi-path environment. In an aspect a signal is transmitted by a transmitter. Multiple copies of the signal are received by a multi-directional receiver based on antenna elements that have a unique antenna pattern for each copy of the signal and where the copies are phase correlated and time synchronized. The copies are deconstructed into components of the reflected and line-of-sight waves of the transmitted signal. The shortest path is selected from among the reflected and line-of-sight waves using the deconstruction.
