System, method and computer-readable medium for estimating direction of arrival of a signal incident on at least one antenna array

A communication apparatus, comprising:

• a plurality of antennas;
• at least one antenna array;
• a computer arrangement;
• and
• a non-transitory, computer-readable medium comprising computer-executable instructions that, when executed by the computer arrangement, cause the apparatus to:
• for each of a plurality of direction-of-arrival candidates,
• receive a plurality of sets of samples, each set comprising a plurality of samples, each sample in each set corresponding to a signal incident on one of a plurality of antennas at substantially the same time as the other samples comprising the same set;
• and
• compute a mean of the envelopes of the sums of the respective sets of the samples;
• estimate a direction of arrival of the signals incident on the antennas based on the computed means for the plurality of direction-of-arrival candidates;
• and
• configure the at least one antenna array based on the estimated direction of arrival.
