Classification: CPC H | IPC H

Claim 0:
1. A receiver system for correlating one or more signals with post-correlation beamforming comprising:
one or more antenna elements configured to receive the one or more signals;
a controller including one or more processors configured to execute program instructions causing the one or more processors to:
duplicate the one or more signals into a first set of duplicated signals and a second set of duplicated signals;
generate one or more correlator outputs based on the first set of duplicated signals using one or more correlators before generating a first set of beams,
generate the first set of beams based on the one or more correlator outputs using a first beamforming module;
generate a second set of beams based on the second set of duplicated signals using a second beamforming module, and generate one or more power estimates based on the second set of beams using one or more power estimators, wherein each one of the second set of beams generated by the second beamforming module corresponds to a respective beam of the first set of beams output by the first beamforming module,
wherein each of the first set of beams corresponds to a respective one of the one or more power estimates; and
divide each of the first set of beams by the respective one of the one or more power estimates using one or more dividers to generate one or more normalized correlations,
wherein the one or more antenna elements comprises L antenna elements, wherein L is an integer greater than or equal to one, wherein L is less than M, wherein M is a quantity of M beam patterns equal to a quantity of the first set of beams,
wherein the one or more normalized correlations are configured to enter a thresholding module configured to compare each of the normalized correlations to a correlation threshold.
