  • MUTUAL COUPLING BASED CALIBRATION
    Publication number: 20230239060
    Abstract: OFDM-BPSK symbol sequences are used for mutual-coupling based phase array calibration. Such substitution allows phase to be estimated more accurately using a given estimation duration without compromising other estimates’ (amplitude and group delay) accuracies.
    Type: Application
    Filed: January 12, 2023
    Publication date: July 27, 2023
