Patent ID: 8477803

Claim:
A method for processing a plurality of received signals in a receiver that each corresponds to a respective RF chain and antenna, comprising: adjusting, by circuitry, a phase of a local oscillator signal based on at least one control signal to provide an adjusted local oscillator signal; mixing the adjusted local oscillator signal with a first of the plurality of received signals to provide a first down-converted signal; mixing the local oscillator signal with a second of the plurality of received signals to provide a second down-converted signal; combining the first down-converted signal with the second down-converted signal to provide a combined signal; providing, by a processor, a first output signal based on the combined signal, wherein the first output signal comprises channel estimates and a timing signal that specifies a location of signal clusters; and generating by a weight generator, the at least one control signal based on the first output signal and sending the at least one control signal to the circuitry, a first RF chain and a second RF chain.
