ANTENNA ARRAY CALIBRATION |
摘要 |
A smart antenna calibration system is disclosed for calibrating an antenna array having a plurality of antennas. Each antenna has a calibration coupler for providing a monitoring signal indicative of a signal passing through a transceiver associated thereof, and a processing unit including at least one signal splitter that splits at least one monitoring signal and a combiner array comprising one or more combiners for combining at least two split monitoring signals from first and second antennas to produce a first combined signal representing an in-phase sum and a second combined signal representing a quadrature sum. A power detector is in communication with the processing unit, which is configured to estimate a power level of the signal passing each of the first and second antennas and the in-phase power and quadrature power of the in-phase and quadrature sums for determining a phase difference of the signal on the antennas. |
