Systems and methods for compensating for transmission phasing errors in a communications system using a receive signal
First Claim
1. A method for correcting transmission phasing errors in an plurality of antenna elements, the method comprising:
- receiving at least a first signal having a first frequency at said plurality of antenna elements at an angle of arrival (AOA);
for at least one of said plurality of antenna elements, identifying an actual fractional wavelength value (ftrue) for the first signal received with respect to a reference location;
obtaining a estimated phase propagation of the first signal at said one of said plurality of antenna elements relative to the reference location based at least on configuration data for plurality of antenna elements; and
updating said configuration data associated with said AOA for said one of said plurality of antenna elements based on the estimated phase propagation and ftrue.

Abstract
A method for correcting transmission phasing errors in an plurality of antenna elements is provided. The method includes receiving at least a first signal having a first frequency at the plurality of antenna elements at an angle of arrival (AOA). The method also includes identifying an actual fractional wavelength value (ftrue) for the first signal received with respect to a reference location for at least one of the plurality of antenna elements, obtaining a estimated phase propagation of the first signal at the one of the plurality of antenna elements relative to the reference location based at least on configuration data for plurality of antenna elements, and updating the configuration data associated with the AOA for the one of the plurality of antenna elements based on the estimated phase propagation and ftrue.
