ANTENNA ARRAY CALIBRATION FOR WIRELESS COMMUNICATION SYSTEMS

摘要

Systems and methodologies are described that facilitate calibrating an antenna array (200) in a wireless network by generating a copy of a transmitted signal or transmitted signal from a transmit chain of an antenna (202, ..., 210) and providing it to a receive chain of one or more antennas in the array for comparison to obtain a gain mismatch measurement. Such comparisons can be performed for each antenna in the array to facilitate obtaining multiple measurements, upon which gain mismatch estimations can be generated. Additionally, the array and/or individual antennas therein can be calibrated based on the mismatch estimates.
