Abstract
A circuit may include an input to receive a signal corresponding to a radio frequency signal received at each element of an antenna array. The circuit may include a beamforming circuit configured to determine two or more samples of a symbol period of the signal from each antenna element and to determine the error estimates for each antenna element based on the two or more samples. The beamforming circuit may be configured to determine one of a line or a plane that best fits the error estimates; determine a direction of arrival of the radio frequency signal based on one or more parameters of the line or the plane and determine a fractional delay for each antenna element based on the direction of arrival of the radio frequency signal.
