Abstract
A system comprises a plurality of antenna elements, a transmitter circuit, and first and second receiver circuits. The transmitter is operable to: transmit, via a first antenna element, a series of signals having a calibration component and each of the signals being generated with a different configuration of the transmitter circuit; and select a configuration for a future transmission based on a signal metric. The first receiver circuit is operable to: receive the signal via a second antenna element; and detect the calibration component in the signal to generate a first calibration signal. The second receiver circuit is operable to: receive the signal via a third antenna element; detect the calibration component in the signal to generate a second calibration signal; combine the first and second calibration signals to generate a combined calibration signal; and generate the signal metric based on the combined calibration signal.
