Abstract
A method and apparatus for mitigating multipath signal distortion using a multi-element antenna array is provided. The multi-element antenna array is used to discriminate between the desired signal and its multipath components based on spatial angle of arrival. A reference signal, provided by the positioning system receiver, is used to compute element weightings that are utilized to null out the multipath components before they reach the receiver.
