Abstract
Aspects of this disclosure relate to systems and methods for calibration of antenna arrays. The calibration may be based on determining a reference value for the beamformer derived from measurements of phase and/or amplitude for each channel within the beamformer. The measurements of phase and/or amplitude can be stored in non-volatile memory. Using a difference between the reference value and the measured values for each channel, a portion of a global configuration table may be copied to each channel's memory. Each channel can be separately calibrated based on the portion of the global configuration table copied to the local memory of each channel.
