Systems and methods for compensating for transmission phasing errors in a communications system using a receive signal

A communications system comprising:

• a plurality of antenna elements;
• and
• an array control system communicatively coupled to said plurality of antenna elements, said array control system comprising:
• a storage element for storing signal data for at least a first signal having a first frequency received at said plurality of antenna elements at an angle of arrival (AOA) and for storing configuration data for said plurality of antenna elements;
• a processing element communicatively coupled to said storage element, said processing element configured for:
• identifying an actual fractional wavelength value (ftrue) for at least one of said plurality of antenna element for the first signal 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.

A computer-readable storage, having stored thereon a computer program for correcting transmission phasing errors in plurality of antenna, the computer program comprising a plurality of code sections for performing the steps of:

• receiving signal data for 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 using a blind source separation algorithm;
• 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.
